Recent field study of Gondwana sediments in the Palar basin near Chennai brings to light the occurrence of assorted size of boulders of extraneous source in argillaceous siltstones. These boulders are regarded as glacial in origin. It is interpreted that icebergs carried such boulders into a pro-glacial lake. Melting of the icebergs resulted in dropping of boulders into the depositional environment. The present study discusses the depositional environment and paleoclimate that prevailed during the deposition of these exotic boulders.Keywords

Studies on the quartz grains of the Campanian-Maastrichtian sediments of the Ariyalur Group of Tiruchirapalli Cretaceous, Tamil Nadu, using Scanning Electron Microscope (SEM) have brought out nineteen distinct microtextures. They have been grouped into features based on their mode of origin. Of these, thirteen are of mechanical and five mechanical and/or chemical origin while one distinctly chemical. The quartz grains of the Ariyalur Group sediments show a wide range of conchoidal fractures, straight steps and arcuate steps formed during the liberation from the metamorphic and igneous source rocks. The microtextures - v's, pits, straight and curved scratches are characteristic of the marine environment. The frequency of these features is higher in the grains from the Sillakkudi, Kallankurichchi and Ottakkovil Formations. Rarity of these features on quartz grains from the Kallamedu Formation is suggestive of variation in transport and depositional conditions. It has been inferred from the microtextures that the source for the quartz grains in the Ariyalur Group sediments has been the nearby Precambrian crystalline basement.Keywords

Cuddalore Sandstone (Mio-Pliocene) of Neyveli and Ariyalur areas has been studied to infer the depositional environment. Granulometrically, poorly to moderately sorted and fine to very finely skewed sandstones are petrographically identified as feldsarenite and litharenite. Source area for the Neyveli sediments included pyroxenite, amphibolite and granodiorite and the Ariyalur sediments were probably, derived from granite and monzonite. Major elemental data show the eugeosynclinal tectonic setting for Neyveli and taphrogeosynclinal setting for Ariyalur area. The overall study suggests a deltaic environment.Keywords

The Post Archaean Australian Shale (PAAS) normalised Rare Earth Element (REE) distribution pattern of a 4m box core from the Lower Bengal Fan clearly exhibits different types of patterns according to the climatic fluctuations of Late Quaternary period. Based on the vertical profiles of REEs, ΣLight REE/ΣHeavy REE ratio, Ce^ and ΣREE the climatic boundaries were further confirmed. The influence of continental sediments with a rugher rate of sedimentation are reflected in higher concentration of ΣREE in glacial periods. The above observations suggest the Late Pleistocene - Holocene boundary at 45-50 cm depth, the Last Glacial Maximum at 50-120cm depth and Glacial (I) stage at 150-290cm depth in the core studied. Warmer periods of Interglacial stages (II) and (I) correspond to 120-150cm and 290-400cm depths.Keywords

Studies on calcium carbonate (CaCO3), trace elements and rare earth elements were carried out on the Kallankurichchi Formation in order to understand the elemental behaviour in marine limestones of the Tiruchirapalli Cretaceous. Variation in EREE content between Sandy Fossiliferous Limestone (SFL) and Fossiliferous Limestone (FL) can be explained as due to the varying amounts of terrigenous material present in the limestones. PAAS (Post Archaean Australian Shale) normalised REE patterns and LaN/YbN ((LaSample/LaShale)/(YbSample/YbShale)) ratios suggest that the terrestrial rocks are the major source for REE in these limestones. The SFL and FL show negative Ce anomalies, with slight variation between these limestones. The negative correlation between CaCO3 and Ce/Ce* values indicates that the observed Ce anomalies are not related to the CaCO3 content in SFL and FL, whereas Ce/Ce* values show positive correlation with detrital elements implying that the observed variations in the Ce anomalies resulted from the variation in the terrigenous material supplied by the continental area. SFL and FL show low U/Th ratio and U content. Low U contents suggest that the oxic condition prevailed in the bottom water and sediment column during the deposition of Kallankurichchi Formation.Keywords

The Maruvattur quarry section (Dalmiapuram Formation) is located near the Archaean-sedimentary boundary at the western margin of the Ariyalur-Pondicherry sub-basin. The lithofacies observed in the quarry include boulder-algal limestone and clastic limestone alternating with siltstone and claystone. This amply reveals that the depositional conditions fluctuated between carbonate facies to fine clastic facies. The coarse clastic materials are not found in the litho-sequence suggesting that the source area reached a peneplanation stage. This stage released only fine clastic materials to develop silty clay and siltstone lithologies. The clastic deposition was fine grained, hence it is interpreted that the depositional basin experienced a calm environment. The limestone units are mostly bedded types pointing out that the older biohermal limestone underwent erosion and redeposited as clastic limestone to form biostromal limestone. The clastic limestone has a few impressions of trace fossils suggesting the slower rate of sedimentation in a comparatively deeper marginal basin.
The Anaipadi river traverse representing Garudamangalam Formation indicates a variable lithological association along the dip direction. The claystone is the bottom most unit of this traverse. The clastic deposition is followed by a muddy carbonate phase, which further indicates a calm neritic environment that existed for sometime before deposition of subarkosic-Arkosic lithofacies towards the top in the traverse. The varied distribution of clastics has been useful to synthesise information on tectonics and sedimentation.
The trilinear plots such as Q, F, L (quartz, feldspar and lithic fragments), and Qm, K, P (quartz monocrystalline, potash and plagioclase feldspars) derived through modal analysis suggest a granitoid source area. The petrographic study and modal analysis suggest that the bottom quartz rich sequence formed in a semi-humid type climate, which gradually became semi-Arid as evidenced by the subarkosic-Arkosic sands towards upper level along the Anaipadi river traverse.

An 8.8m of consolidated core obtained below 20m of unconsolidated marly sediments near the Tuticorin coast was subjected to detailed stratigraphic, petrographic and geochemical analyses. A lithological succession with eight minor Litho-Units in ascending order has been established: Shell limestone, lower sandy shell limestone, calcareous conglomerate, middle sandy shell limestone, algal limestone, upper sandy shell limestone, calcareous sandstone and calcrete. The petrographic types are mostly the variants of wackestone, boundstone, arenite and calcrete. CaO is high in shell limestone, algal limestone and sandy shell limestone and proportionately SiO2 is low in these litho-units. Algal limestone is enriched in MgO content, The conversion of high Mg-calcite to low Mg-calcite, aragonite inversion as well as mixed zone diagenetic setting resulted in depletion of both δ13C and δ18O, The petrographic evidence and assemblage of the juvenile gastropods, pelecypods, bryozoans, algae and benthic foraminifers suggest a fluctuating inner neritic to a moderately high saline lagoonal depositional environment. The absence of sparry calcite indicates an early marine to mixed zone diagenetic settings and the shell limestone unit experiences a moderate burial diagenesis while the upper units experience a shallow burial diagenesis. A Late Tertiary age is assigned to the shell rich limestone unit.Keywords

Quartz grains from Kudankulam Formation were studied using Scanning Electron Microscope(SEM), which brought out eighteen microtextures. The quartz grams of Kudankulam Formation show different types of conchoidal fracture, arcuate steps, V-shaped patterns, pits and sub angular to Sub-Rounded outline. The presence of conchoidal fracture and arcuate steps suggest that these quartz grains were derived from the nearby crystalline source. The microtextures such as V-shaped patterns, pits, straight and curved scratches are characteristic of marine environment.Keywords

Petrography, fluid inclusions and surface texture studies have been carried out on the Nimar Sandstone, which have provided fruittful results on pravenance and depositional environment The detrital omposition of sandstones plotted in the Q-F-L diagram suggests cratonic orrgin The modal percentages of different types of quartz plotted in the diamond diagram Indicate that these sediments were derived from the low-grade metamorphic rocks Quartz grains show randomly distributed primary inclusions, small trails of pseudosecondary inclusions and needle-shaped solid phases also support that the source rocks are mainly low-grade metamorphc rocks The surface textures on quartz grains reveal the presence of twenty-two distinct surface textures Based on their origin, these textures are grouped into three types viz I) thirteen features that show mechanical origin, II) five features that exhibit mechanical and/or chemical origin and III) four features that reveal chemical (precipitational)origin The quartz grans exhibit conchoidal fractures, arcuate steps, and fractured plates/planes, which resulted during the liberation of these grains from the crystalline formations They also exhibipt petransportational features such as pedological overgrowths, silica globules, flower and pellicles, which are indicative of short transportation and rapid deposition of these sediments Vs, straight and curved scratches are more common on the quartz grains from the upper Nimar Sandstone (whtch are characteristic features of marine environment), whereas the lower frequency of these features on the quartz grains from the lower Nimar Sandstone suggest fluvia depositional environments.Keywords

Petrographic and geochemical studies of the Late Maastrichtian-Early Palaeocene sediments of Kallamedu and Niniyur Formations of Tiruchirapalli have brought out significant results on palaeoweathering and source area characteristics. In the bivariate plot of SiO2 vs Al203+K20+Na203 all the clastic samples fall in the arid field indicating that the arid climatic condition prevailed in the source region during the deposition of these sediments. In the Al203 vs Na20 plot, the clastic samples fall between low grade Archaean shale and post-Archaean shale suggesting that the detrital components have been derived from low to moderately weathered terrain. The Chemical Index or Alteration of clastic sediments range from 40 to 69 with lower values for sandstones (40 to 57) than for silty shale and shale (61 to 69) and this indicates that the source rocks have undergone low to moderate chemical weathering. In QFL diagram, most of the sandstones fall in the field of cratonic interior basin which indicate that these sediments were deposited in the stable craton. SiO2/Al203 ratios are high observed for sandstone, silty shale and shale, with a range starting from 3.15 to 8.75. The higher ratios of SiO2/Al2O3 in clastic sediments indicate a largely felsic rock provenance. Major element data indicate an overall taphrogeosynclinal continental rift-related depositional basin.Keywords

The results obtained from stable isotope study of Neogene carbonates of Kudankulam, Tamil Nadu show negative values for δ13C, which range from -2.6‰ to -9.7‰ PDB. The δ18O values range from -4.5‰ to -11.4‰ PDB. The depleted nature of the δ18O and δ13C values suggests the strong effect of meteoric diagenesis in the Kudankulam carbonates. Standard bivariate plots of δ18O versus δ13C for carbonate materials/rocks helped to identify their depositional and diagenetic environments. Petrographic study points out large-scale emplacement of ferroan sparry calcite cement into vugs and other leached cavities.Keywords

Illite and smectite are the major clay minerals, whereas kaolinite and chlorite are present in small amounts in the sedimentary rocks of Ariyalur Group. The samples belonging to Ariyalur Group exhibit LREE enriched and flat HREE patterns. These samples show high ratios of CLREEIZHREE (7.65 to 19.42) which indicate that these sediments were derived from the felsic source rocks. The persistence of uniform REE patterns for the clastic samples of four formations of Ariyalur Group distinctly implies a hoinogenous nature of the source rocks. The Sillakkudi and Kallankurichchi Formations (Campanian - early Maastrichtian) exhibit high content of illite which indicate that the sediments were derived from pre-existing rocks (granites and gneiss), subjected to physical weathering in a tempcrate climate. A sudden change in illite content was noticed in Ottakkovil Formation, which probably points out a change of climate from cold to warm during middle Maastrichtian. The abundance of pedogenic smectite in the Kallamedu Formation suggests warm climate with drylwet cycles.Keywords

Rhodoids are laminated algal nodules generally found in shallow marine environment. Algal crusts and nodules are poorly exposed between Kudankulam and Sattankulam in the coastal area near Cape Comorin. The thickness of the bed of algal limestone varies from 0.5 to 1.5 m. The occurrence of abraded rhodoids with lack of terrigenous material suggests moderate to high energy depositional condition. The present study of the rhodoids, points out that the Neogene tectonic activity has played a significant role for the development of algal limestone and rhodoids in the study area.Keywords

An ooid-rich limestone band of Sillakkudi Formation is encountered in a well section near Ariyalur. The ooids are believed to be deposited in a marine regime. They contain berthierine as the major mineral and haematite, siderite and quartz as minor minerals. They exhibit alternate rings of berthierine and haematite which shows that these minerals were developed under changing physico-chemical conditions. In the present paper, the petrographical characters, mineralogy, origin and depositional environment of the ooids are discussed.Keywords

Unfortunately the global conventional fuels in reserves are running out while the world energy consumption is increasing very fast. All scientists agreed that solar energy is one of the best solutions for energy supply in many parts of the world. The aim of this work is to experimentally investigate the solar water heater at various flow rates integrated with phase change material (PCM). Abundantly available solar energy utilization for domestic and industrial application is hindered because of its intermittent nature. The thermal energy storage (TES) system using both the sensible and latent heat has many advantages like large heat storage capacity in a unit volume and its isothermal behaviour during the charging and discharging processes. The system consists of two simultaneous functioning heat absorbing units. One of them is a solar water heater sensible heat storing unit and the other a latent heat storage unit consisting of phase change materials (OM53). The storage unit stores the heat in phase change materials during (charging period) the daytime and supplies hot water, when solar radiation is not available. The experiment was conducted with different types of flow rates and verified energy storage time period in the evening hours.Keywords

Leakage power of CMOS VLSI Technology is a great concern. To reduce leakage power in CMOS circuits, a Leakage Power Minimiza-tion Technique (LPMT) is implemented in this paper. Leakage cur-rents are monitored and compared. The Comparator kicks the charge pump to give body voltage (Vbody). Simulations of these circuits are done using TSMC 0.35μm technology with various operating temper-atures. Current steering Digital-to-Analog Converter (CSDAC) is used as test core to validate the idea. The Test core (eg.8-bit CSDAC) had power consumption of 347.63 mW. LPMT circuit alone consumes power of 6.3405 mW. This technique results in reduction of leakage power of 8-bit CSDAC by 5.51mW and increases the reliability of test core. Mentor Graphics ELDO and EZ-wave are used for simulations.Keywords

Flip-flops are the basic building blocks of any sequential circuits which occupy the maximum area in a circuit. So the robustness of the system greatly depends on the reliable operation of the flip-flop. In this work the PowerPC 603 flip-flop is simulated and analyzed to measure its reliability against variations in supply voltage and temperature. Performance analysis has been made by having Power, Delay and PDP as Figures of Merit. The acquired simulation results revealed the different sources of power consumption in different scenarios. The simulated results using finer technologies with Synopsys HSPICE prove that PowerPC 603 is a resilient flip-flop for all corners.Keywords

Design of an analog circuit depends on several factors such as design methodology, good modeling and technology characterization. This work focuses on designing a high speed (1.6GHz) latched comparator with low power consumption suitable for ADCs in SoC applications. The latched comparator is designed with StrongArm latch as the primary decision and amplification stage followed by a latching element to drive the output load. The StrongArm latch is a proven circuit topology suitable for all seasons. The zero static power consumption of StrongArm latch is exploited to design a low power comparator. The output latch is used to hold the previous output value during the tracking time of the comparator. The designed comparator achieves zero setup time at a clock frequency of 1.6GHz and produces digital output with a maximum delay of 180ps.The comparator is implemented with SAED 32nm technology libraries. The performance has been analyzed using HSPICE simulator.Keywords

In this paper, an inverter based transconductor using double CMOS pair is proposed for implementation of a programmable bandpass filter suitable for Digital Radio Mondiale (DRM). Major contributions of this paper are: proposal for operating the transconductance (Gm) stage in sub-threshold region in order to minimize the power dissipation, proposal for switching in different Gm cells with suitable dummy stages for varying the centre frequency (F-tuning) and filter pass band (Q-tuning), proposal for a digital tuning technique for the filter based on phase comparison method for PVT compensation. The filter circuit is based on a biquad Gm-C topology, which is designed and implemented on CMOS 0.18μm technology with 1.8V supply using gm/Id design methodology. The post layout simulation results demonstrate the tunability of the centre frequency from 2MHz to 11MHz with quality factor tunable up to 50, which meets the requirements of DRM (upto 30MHz). Post layout simulation results show that the filter exhibits an in-band dynamic range of 53dB at gain of 7dB. An input IP3 of up to 28dBVp is achieved for an input signal of 100mVp. The SFDR over the entire bandwidth is 57dB. These features are obtained for a total power consumption of less than 300 μW from a single 1.8 V power supply with an estimated silicon area of 0.3mm2. The proposed approach guarantees the upper bound on THD to be -40dB for 300mVpp signal swing. The use of inverters with double CMOS pair results in 34dB higher PSRR compared to those using push pull inverter.Keywords

The only criteria that are used to evaluate the various neural network-based object identification models that are currently in use are the inference times and accuracy levels. The issue is that in order to put these new classes and situations to use in smart cities, we need to train on them in real time. We were not successful in locating any research or comparisons that were centered on the length of time necessary to train these models. As a direct consequence of this, the initial reaction times of these object identification models will consistently be quite slow (maybe in days). As a consequence of this, we believe that models that put an emphasis on the speed of training rather than accuracy alone are in significant demand. Users are able to gather photos for use in training in the present by utilizing concept names in online data collection toolkits; however, these images are iconic and do not have bounding boundaries. Under these conditions, the implementation of semi-supervised or unsupervised models in a variety of smart city applications might be able to contribute to an improvement in the precision of data derived from IoMT. In this study, we categorize the video clips into their appropriate classes using an improved ensemble classification model.Keywords

This paper presents a resource allocation technique for industrial applications for 6G networks, which are characterised by the presence of many heterogeneous parameters that have an effect on the quality of data transmission. The purpose of the project is to achieve the greatest possible efficiency in the application of the resources that are presently while achieving a higher level of control over a diverse collection of sensing nodes operating within a hybrid network. The system model that has been proposed is a workable option for efficient resource allocation. The performance of the proposed method, in addition to similarities to the performance of other methods has been analysed. The proposed methods offer performance that is comparable to or better than the baseline, while simultaneously significantly reducing the SI exchange overhead and improving the system resilience to sensing intervals, some of which may be unavoidable in practise.Keywords
