Optimization of energy exhaustion for Smart Camera Network in vision task

Abstract: Smart Camera Network (SCN) mainly has different applications based on the surveillance, security and safety with limited energy, power and memory. Normally cameras operate under limited power resources. To extend the lifetime of smart camera, it is required to reduce the energy consumption in an effective way. This paper mainly presents adaptive energy consumption of smart camera network, by assigning distributed and adaptive utility function for vision tasks. The switching of vision tasks between active, idle and sleep modes takes place based on the frequency and duty cycle. Switching of tasks is mainly done on the basis of availability of energy resources. Algorithm for Multitask allocation in smart camera network is assigned in such a way that results in the reduction of energy consumption without minute changes in the performance of the target tracing and representation. Algorithms that are assigned for each task must be effective and the weight is varied in accordance with the threshold values for energy resources. This paper represents, how a little change in the task allotment, algorithm and energy resources for smart camera results a major role in the grown of implementation of vision task and life time.

Business Model Based Pricing Strategy for Pharma Products in Southeast Asian Region

Abstract: Purpose To study pharmaceutical product procurement and pricing system in Southeast Asian countries and challenges, factors influencing and industry practices of the pricing. Methodology Study was carried out based on secondary data published in various journals, domain knowledge of the author and industry experts' inputs on the various business models and pricing practices. Findings Factors influencing pharmaceutical products pricing in markets under study including the government policy, distribution practices, selling expenses and industry practices. Research implications This article provides generic observations of product pricing in the context of prevailing regulatory and business environment. Individual strategies differ based on country, company, business model product and market strategy. Further study can be taken up to decide a product pricing model for individual model. Practical implications Provides basic reference for healthcare system, pharma product procurement practices and pricing strategies for industry and academia. Social implications Helps Industry and regulatory authorities in rationalising the generic drugs prices and increase the access to affordable medication which will address unmet needs of patients. Originality It is an original study carried out to understand and review on how industry is arriving at a business model based pricing for pharma products in Southeast Asian countries.

Wideband Dual Frequency CPW Fed Fractal Antenna For Wireless Applications

Abstract: A Wideband Dual Frequency CPW feed rectangular patch antenna has been designed for the C, X and Ku band applications with an operating frequency range of 3.9GHz to 7.2GHz covering 3.3GHz of bandwidth and 11.2GHz to 13.1GHz covering 1.9GHz of bandwidth. Patch has been etched with slots in a periodic manner which led for the generation of dual wideband bandwidths. Flame Retardant Glass epoxy is taken as substrate material which is having a thickness of 1.6mm and a 50Ω stripline has been used to excite the antenna. Fractal technique has been implemented to attain the wide bandwidth of operation. The overall dimension of the antenna is 27.4mm×20.8mm×1.6mm. The Proposed antenna is having wide bandwidths covering the C, X and Ku band frequencies ranging 3.9GHz to 7.2GHz covering 3.3GHz of bandwidth and 11.2GHz to 13.1GHz covering 1.9GHz of bandwidth with a return loss value less than -10dB for entire bandwidth. Commercially available 3D simulator Ansys HFSS software has been used to design the proposed antenna.

The Internet Of Things On Neural Networks Provides Intelligent Healthcare Management For Diabetic Patients

Abstract: A newly developed health system for a diabetic is described in this study, which tracks their health based on blood sugar levels, heart rate, food consumption, sleep duration, and activity. To explain, this technology is continually receiving variables via sensors and processes them using a neural network to analyze the data, yielding four things like health threats: minimal, moderate, extreme, and severe. The spectrum of genetic risk varies depending on the customer's kind and past health histories. Furthermore, if a patient's health state is at high or extreme danger, an instantaneous phone call/SMS notice is made to the patient's family, including the patient's position. In addition, it alerts patients to the nearest hospital if they are in danger. This technique has been successfully tested on 25 people with diabetes, with reliability of 84.41 percent in determining the appropriate level of risk, which is a highly adequate standard of determining risk factor status.
