Abstract:
SIP is one of the mainstream protocols in the VoIP. A majority of SIP’s security mechanism only provides a single direction authentication from server to client such as HTTP digest authentication. To improve the present situation, a new security mechanism of SIP based on the improved HTTP digest authentication is put forward in this study. This improved security mechanism not only provides a double direction authentication between the server and client but also reduces the expenses of the server and increases the authentication efficiency thanks to its low computational complexity.

Matrix-type granulators have a pressing mechanism consisting of a perforated ring die and rollers that press biomass into the die channels (dies). At high pressures of 40-90 MPa, molecular adhesion (dry extrusion process) occurs between biomass particles in the channels, and intense friction of the material against the walls occurs, which increases the temperature of the pellets to 80-105°C. During operation of the mechanism, technological violations of the “roller-biomass-matrix” system occur in the form of jamming (non-passage) of the material through the matrix channels.

Abstract:
This paper presents a detailed exergy analysis of homogeneous charge compression ignition (HCCI) engines, including a crank-angle resolved breakdown of mixture exergy and exergy destruction. Exergy analysis is applied to a multi-zone HCCI simulation including detailed chemical kinetics. The HCCI simulation is validated against engine experiments for ethanol-fueled operation. The exergy analysis quantifies the relative importance of different loss mechanisms within HCCI engines over a range of engine operating conditions. Specifically, four loss mechanisms are studied for their relative impact

Abstract:
Abstract A compressor casing treatment with circumferential casing grooves (CCGs) is studied in detail. The primary objective of the current paper is to unearth the main driving fluid mechanism that changes the stall margin in a transonic compressor with CCGs. Large Eddy Simulation (LES) is applied to calculate the transonic compressor flow fields with and without CCGs. Detailed comparisons between measured and computed flow fields show that changes in flow structures due to CCGs are very well represented with LES. The measured data show that flow blockage generation in the tip gap area is red

Abstract:
The research on thermotolerance acquisition in broiler chickens by temperature conditioning early in life was focused on the following objectives: a. To determine the optimal timing and temperature for inducing the thermotolerance, conditioning processes and to define its duration during the first week of life in the broiler chick. b. To investigate the response of skeletal muscle tissue and the gastrointestinal tract to thermal conditioning. This objective was added during the research, to understand the mechanisms related to compensatory growth. c. To evaluate the effect of early thermo cond

Abstract:
This project developed conceptual and empirical frameworks to analyze the water management politics as water scarcity increases. The analyses showed that increased scarcity will tend to encourage a transition from systems in which water is allocated administratively to water trading. However, transaction costs and political economy considerations placed barriers on the introduction of markets. The recent droughts - both in Israel and California were shown to cause an increase in water use efficiency by adoption of modern technologies and improvement of water conveyance systems.

Abstract:
Onboard image analysis enables real-time autonomous capabilities for unmanned platforms including aerial, ground, and aquatic drones. Performing classification on embedded systems, rather than transmitting data, allows rapid perception and decision-making critical for time-sensitive applications such as search and rescue, hazardous environment exploration, and military operations. To fully capitalize on these systems’ potential, specialized deep learning solutions are needed that balance accuracy and computational efficiency for time-sensitive inference.

Abstract:
An investigation of catalyst performance during the initial aging process, providing insight into the deactivation rate of the catalyst and assisting in predicting the operational lifetime of the catalyst was preformed. The information gained through the test program provides a mechanism to assist in developing new technologies geared at reducing engine emission while providing improvements in efficiency, reliability, and operability for the aging industrial reciprocating engine fleet.

Abstract:
The necessity to improve broiler thermotolerance and live performance led to the following hypothesis: Appropriate comprehensive incubation treatments that include significant temperature management changes will promote angiogenesis and will improve acquisition of thermotolerance and carcass quality of heavy broilers through epigenetic adaptation. It was based on the following questions: 1. Can TM during embryogenesis of broilers induce a longer-lasting thermoregulatory memory (up to marketing age of 10 wk) that will improve acquisition of thermotolerance as well as increased breast meat yield

Abstract:
The West African Economic and Monetary Union (WAEMU) has been engaged in an ambitious project to harmonise its members’ domestic tax systems since 1994. After 30 years, this study aims to highlight the successes and challenges associated with WAEMU’s tax harmonisation policy, and to examine its application in practice. Although WAEMU has succeeded in establishing a solid normative framework and has achieved its primary harmonisation goals, the success of a tax policy is measured by its actual implementation. In this respect, the results are mixed. It is therefore essential that WAEMU intensifi
