Abstract

A filter is a key and critical component for all types of wireless communication receivers, which are used to reject the noises (unwanted frequencies) in accordance with the applications. Band pass filters enable operation of any given module in a particular frequency range. In this paper, a compact microstrip band pass filter is proposed with operating range from 2.7 to 10.7 GHz for Ultra-Wide band (3.1 to 10.6 GHz) applications. The Chebychev elliptic function filtering method is employed. Two open circuited stubs are used to achieve the upper transmission loss and coupled micro strip structure is used to reduce transmission loss. The designed filter has insertion loss greater than -1 dB and return loss lower than -10 dB in pass band. The filter is designed with dimensions of 10mm x 9mm x 1.6mm on FR4 (εr = 4.3) substrate. The sharp cut-off at lower and upper stop bands has been achieved by proper tuning of the widths and lengths of the open circuited stubs. Bandwidth of about 8 GHz and a flat group delay in the pass band have been achieved. In view of its compactness, this filter can be easily integrated with all communication devices. The designed band pass filter has potential and promising application in UWB (Wi-Fi, Wi-Max, WLAN and ITU) applications.

Abstract

This project presents AN economical implementation of a high speed number victimisation the shift and adds technique of Baugh-Wooley number. This parallel number use lesser adders and lesser reiterative steps. In this we tend to designed for 64x64 bit Baugh Wooley number. As a results of that they occupy lesser house as compared to the serial number. This can be vital criteria as a result of within the fabrication of chips and high performance system needs parts that area unit as tiny as attainable. Experimental result demonstrate that the planned circuit not solely improves the correct performance however additionally reduces the hardware complexness and additionally less power consumption that's dynamic power of fifteen.3mW and most clock amount of three.912ns is needed that is extremely economical as compared to the reference paper[2]. This paper presents the planning and implementation of signed-unsigned changed Booth cryptography (SUMBE) number. This changed Booth cryptography (MBE) number and therefore the Baugh-Wooley number perform multiplication operation on signed numbers solely. The array number and Braun array multipliers perform multiplication operation on unsigned numbers solely. Thus, the need of the trendy system may be a dedicated and extremely high speed distinctive number unit for signed and unsigned numbers. Therefore, this paper presents the planning and implementation of SUMBE number. The changed Booth Encoder circuit generates 0.5 the partial product in parallel. By extending sign little bit of the operands and generating an extra partial product the SUMBE number is obtained. The Carry Save Adderr (CSA) tree and therefore the final Carry Lookahead (CLA) adder won't to speed up the number operation. Since signed and unsigned multiplication operation is performed by a similar number unit the desired hardware and therefore the chip space reduces and this successively reduces power dissipation and value of a system.

Abstract

In this paper, simple techniques are been proposed and investigated successfully to overcome the basic limitations of gain, bandwidth for a microstrip antenna and mutual coupling for a microstrip antenna array. A meandered E shape patch antenna with a air cavity is proposed to enhance gain and bandwidth. To reduce mutual coupling an Electromagnetic band gap structure has been proposed. Coax feed has been used for excitation. The meandered patch provides band width enhancement and the air cavity along with a thick aluminum ground plane combindly provided gain enhancement. E shaped patch has been formed by considering a basic rectangular patch and by etching slots at the edge of the patch. The simulated results show a bandwidth of 89MHz ranging from 1.30GHz to 1.39GHz with a maximum gain of 8.37dB at the operating frequency of 1.35GHz. The antenna has been designed over a RT Duroid 5880 substrate with a dielectric constant of 2.2 and thickness of 62mil. Antenna Design and simulation studies are carried out in Ansys HFSS software.

Abstract

Non-Steroidal Anti-inflammatory Drugs (NSAIDs) are used as over-the-counter drugs for Analgesic and Antiinflammatory conditions. They inhibit prostaglandins synthesis by acting on Cyclooxygenase enzymes in the Arachidonic cascade which causes various abnormal effects like peptic ulcers, Gastrointestinal bleeding, sodium and water retention, hypertension, hemodynamic kidney injury, nephrotoxicity, stroke, and myocardial infarction when used for a longer duration, especially in older patients/comorbidities patients/ pre-existing renal disease patients. This is because in older patients decrease in glomerular filtration rate and comorbidity conditions increase the risk of NSAIDs and cause Acute Kidney injury, Tubulointerstitial nephritis, and chronic kidney injury. NSAIDs do not cause much risk in patients who are young, without pre-existing kidney disease and without comorbidities. Physicians should educate patients with caution on the usage of NSAIDs for longer periods and should prescribe drugs in a dose-dependent manner.
