Abstract

As mobile networks expand their bandwidth, mobile phones, as with any other Internet device, become substantially exposed to Internet security vulnerabilities. Public key cryptography is a primary concept in implementing wireless device security. This paper describes the applicative use of PKI in current and future mobile phone applications, and shows how the standard-compliant implementation of cryptographic algorithms, enables wireless devices to become PKI-enabled. The Wireless Application Protocol is a leading technology for companies trying to unlock the value of the Mobile Internet. The WAP model introduces a Gateway that translates between WAP and Internet protocols. This Gateway is typically located at the site of the mobile operator, although sometimes it may be run by an application service provider or enterprise. WAP enables such capability via use of a crypto API, referred to as the WMLScript Crypto API. WMLScript is a simple script language that allows client-side processing, and instructs the client device to invoke application-level functions.

Abstract

Nowadays, huge amount of domestic and industrial waste is being discharge to the surface or groundwater which poses a great threat to the mankind. Hence, treatment of any kind of wastewater to produce effluent with good quality is necessary. In this regard, choosing an effective treatment system is much important. Sequential Batch Reactor (SBR) holds a special place in the wastewater treatment which is a modified version of activated sludge process. An SBR operates in a true batch mode with equalization, aeration and sludge settling, all occurring in the same tank. The removal of organic load in the reactor mainly depends on the duration of reaction phase, so it is essential to determine the optimum duration of reaction phase. In the present study, an attempt was made to optimize the duration of the reaction phase in SBR for the treatment of domestic wastewater and removal efficiency of COD, BOD and SS were studied. To optimize the duration of reaction phase in SBR, a 100-litre capacity laboratory scale model was fabricated and operated for 100 cycles for various reaction phases. The percentage removal efficiency of BOD, COD and SS for various reaction periods was calculated and the graph between reaction percentage removal efficiency of BOD, COD and SS were drawn, the results were utilized to determine the optimum reaction period for effective treatment of domestic wastewater with high removal efficiency using SBR.

Abstract

Hand washing for hand hygiene is the art of cleaning the hands with or without the use of water or another liquid, or with the use of soap, for the purpose of removing soil, dirt, and/or microorganisms. The main medical purpose of washing hands is to cleanse the hands from pathogens (including bacteria or viruses) and chemicals which can cause personal harm or disease. This is especially important for people who handle food or work in the medical field, but it is also an important practice for the general public. In response to this concern, we formulated the antibacterial Liquid soap. Experiment was performed by selecting the herbs which were reported to have antibacterial activity. They are Ocimum sanctum and Eugena caryophyllus. Formulated liquid soaps were evaluated for physical parameters like colour, fragrance and chemical parameters like pH, % Free alkali, Test for chlorides, Foam height, Foam retention, Alcohol insoluble matter, Microbial count etc. and the obtained results were in the acceptable limits except foam height and foam retention as we are not using SLS.

Abstract

Objective: To remove the noises occurred in the bio medical pictures with less computation time. Methods: An innovative technique called Parallel Fuzzy Inference System (PFIS) is introduced for image denoising in the medical images. This method takes input training images, process a dissimilar neighbourhood association between the center pixel and generates the fuzzy inference rules. These rules are distributed to the nodes for simultaneous execution. Then, the type-1 interval fuzzy set is submitted to the resultant defuzzifier module which will decode it into scalar value. If it is impulse pixel, the noise filter is used to reduce the noise. Results: The improvement of the PFIS technique is evaluated by using the medical images. PFIS method shows high efficiency when matched with the existing Type-2 Fuzzy Logic (TFL) based impulse detector for impulse noise removal. In the PFIS method, the fuzzy rules are generated analyzing the medical images and these rules are processed simultaneously. If the noise density is 75%, the Mean Squared Error (MSE) in PFIS is 59.48, the False Classification Ratio (FCR) is 3.25 and the computation time is 740 ms. According to the comparison and the results from the experiment shows that the proposed method has high efficiency. Conclusion: The findings demonstrate that the PFIS is presented and this method has high efficiency in terms of MSE, FCR and computation time.

Abstract

The Heart Diseases cause immeasurable death worldwide as a result of the rise within the aging population and also the rising of attention prices. This wearable is used to monitor the patient heartbeat rate and ECG. By using the rate identify the patient condition. These sensing rate are directly send to the doctors or to the concern relative. If patient attain a critical situation this wearable send alert message to the nearest ambulance doctor and their relatives. By using this wearable avoid death rate. There's additionally a requirement of quality attention from remote locations. Technological advancements within the field of medical physics and communication will facilitate decreasing the price of attention. The purposed system is inspired from the existing systems like heart monitoring and alert system with four computing and managing the traffic for an ambulance in India and ECG monitoring system.  This combined monitoring and alert system and ECG monitoring system save the patient life.
