High quality of service (QoS) requirements in multi-priority wireless sensor networks pose new challenges to the Internet of Things (IoT). In a multi-event wireless sensor network (MWSN), nodes generate different types of data packets with different priority such as urgent (high priority) or normal (low priority), with different traffic proportion.

Rice (Oryza sativa L.) is one of the staple cereal crops of the world and it is one of the main sources of carbohydrates for nearly one-half of the world's population. So, an increase in rice yield to satisfy human needs is a pressing requirement. Agronomic characters such as high plant, length of panicle, length of flag leaf, number of seed per panicle, the weight of thousand rice, length and width of rice and tolerance to salt are the deciding factor for yield in rice.

This paper aims to develop an effective method for reduction and decomposition on large matrices with low required computational resources and fast processing times. Our contribution is to design a PCA-SVD hybrid method that dividesthe feature extraction into two phases: PCA-based size reduction and SVD-based decomposition. In our method, PCA is first applied to a large matrix to extract its important components

ESI greatly enhanced the ability to characterize protein and peptides by MS.
ESI requires the sample of interest to be in solution- flow in to the ionization source region.
To ionize the sample, high voltage is applied, result in the sample becoming positively or negatively charged; however, positive ionization is used primarily in the analysis proteins and peptides.
As it exits the spray tip, the solution produces submicrometer-sized droplets containing both solute and analyte ions. The sample is then desorbed of solute prior to entering the analyzer region....

I. Introduction An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.

This thesis presents a pro–active research work motivated by the prospect of the imminent implementation of the regulatory requirement for pedestrian protection, Global Technical Regulation–9 (GTR–9) (United Nations Economic Commission for Europe 1998) in the near future. To meet the performance criteria for pedestrian protection head impact, it is vital to incorporate the required design parameters into the hood design process at an early stage. These main design parameters are architectural and changing them late in the vehicle design process is very expensive and difficult to implement.

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.

The International Accounting Standards require entities to report useful and accurate information, enabling shareholders and others to make informed investment decisions. This research investigates the array of factors that influence the investment decision-making of shareholders in the Stock Exchange of Thailand (SET). The research employed a mixed research methodology that combines quantitative and a qualitative analysis to obtain empirical data on the factors that impact on Thai shareholders investing in large asset-based industries in the SET.

In this paper a molecular dynamics simulation of nano-metric cutting of copper with a diamond tool is presented. MD simulations require the determination of the interaction of the involved atoms through a function of potential for the materials involved in the analysis and the accurate topography of the studied area, leading to high demand of computational time.
