Recently, agile methodologies have been adopted in many application areas of developing software. Since the quality is an inherent factor of the right agile product development, so the use of agile leads to increase the quality of software. The objective of this study is to explore the quality that gained by adopting agile methods and how can be achieved. A systematic mapping study (SMS) is conducted to answer five research questions related to the study topic.

The purpose of this study is to simulate and analyse the functioning of a solar desalination system coupled with four flat plate solar collectors with each having a surface of 3m2. To achieve this work, we have modeled the equations of heat balances by numerical simulation by using Matlab, The results obtained, from the resolution of equations governing the thermal transfer in the distiller, show that the total production of drinking water is 90 l / day, that the first stage of the system produces about 29 l of distilled water, the production decreases with the stages, it varies from 29 kg to 13 kg (variation of 16 kg), it was also found that stages 1 to 4 produce about 36%, 28%, 21% and 15% of the overall production, respectively. And the overall hourly efficiency of the order 0.52 kg / m2.h. The overall energy performance obtained shows, on the one hand, the good operation of the solar distiller and, on the other hand, the production of drinking water that meets the needs of the beneficiaries of the Douar Al Hamri, where the system of solar desalination will be installed.
本研究的目的是模拟和分析太阳能脱盐系统的功能，该系统与四个平板太阳能集热器相结合，每个集热器的表面为3平方米。为了完成这项工作，我们利用Matlab对热平衡方程进行了数值模拟，结果表明，从控制蒸馏器传热的方程中得到的结果表明，饮用水的总产量为90 l /天，系统的第一阶段生产约29 l蒸馏水，产量随着阶段的增加而减少，从29 kg到13 kg不等(变化16 kg)。研究还发现，第1 ~ 4阶段的产量分别占总产量的36%、28%、21%和15%。而整体小时效率约为0.52 kg / m2.h。所获得的总体能源性能一方面表明太阳能蒸馏器运行良好，另一方面表明生产的饮用水满足将安装太阳能脱盐系统的Douar Al Hamri受益者的需要。

We report here bands structure and the effective mass, in the direction of growth and in plan of HgTe (d1= 4.5 nm)/ CdTe(d2=4.8 nm) superlattice done in the envelope function formalism. We investigated Hall Effect with the help of the density of states and the Fermi level as a function of temperature. We found that temperature generated transitions from quasi bidimensional holes (Q2D) to three dimensional (3D) electrons and p type to n type conductivity respectively. When T increases, Eg increases and the cut-off wavelength λc decreases, with 5.06 μm < λc < 6.3 μm and the cut-off frequency 47 THz < fc < 59 THz. This sample can be used as a mid infrared terahertz detector. This superlattice is better than the random alloy Hg0.72Cd0.28Te for application as infrared detector at 21.88 K. These results are a guide for the design of infrared nanostructures detectors.

A system of partial differential equations modelling the cell division by considering an age structure within a population of cells controlled by many complex regulatory mechanisms is analysed. The analysis of the model is based on the perturbation theory for dual semigroups of operators applied to a renewal equation of the type u(t) = ϕ(ut). The operator ϕ associated with the model is determined and various properties are established to conclude the AEG property associated to the PDE model. Furthermore, the associated Malthusian coefficient is characterized by only using properties of ϕ.

The advancement of the internet of things (IoT) technologies such as wireless sensor network (WSN) have accelerated the development of routing protocols suited for low power and lossy networks (LLNs). Routing Protocol for Low-Power and Lossy Networks (RPL) is a proactive dynamic routing protocol based on IPv6 with two known objective functions (OFs): Objective Function zero (OF0) and Minimum Rank with Hysteresis Objective Function (MRHOF). This paper provides an overview of this protocol with a performance study of the two OFs used in RPL. Several scenarios have been tested with 30, 60 and 120 nodes, and five parameters of comparisons were selected (Expected Transmission Count, number of hops, convergence time, power consumption and duty cycle), to our knowledge all the present works on the performance of this protocol never passed the wall of 100 nodes, and the data rate and latency were the main focus, we wanted to make a profound study by focusing on other important parameters with less focus.
无线传感器网络(WSN)等物联网(IoT)技术的进步加速了适合低功耗和有损网络(lln)的路由协议的发展。低功耗损耗网络路由协议(Routing Protocol for Low-Power and Lossy Networks, RPL)是一种基于IPv6的主动动态路由协议，有两个已知的目标函数:目标函数零(OF0)和最小时延目标函数(MRHOF)。本文概述了该协议，并对RPL中使用的两种OFs进行了性能研究。在30、60和120个节点的情况下测试了几种场景，并选择了5个比较参数(Expected Transmission Count, hops数，收敛时间，功耗和占空比)，据我们所知，目前关于该协议性能的所有工作都没有超过100个节点的墙，数据速率和延迟是主要的焦点，我们希望通过关注其他较少关注的重要参数来进行深入的研究。

The present paper aims to study the function of the high voltage power supply three-phase in various industrial applications specified in microwave application. The microwave oven transformer is essential components used in power supply systems, the previous model used to feed a magnetron per phase. The new model proposed to use different design to feed two magnetron instead of one. Hence the new transformer will take a new variables, which should be dimensioned take into account the constraint imposed to avoid the disruption of the mganetrons. These different model products differ in their design parameters such as core flux density, dimensions of windings, secondary or primary number of turns etc. the results obtained are compared with those of the previous model design. This new system is composed of three phase leakage flux transformer, each phase supplying two cell, composed of a capacitor and a diode, which multiplies the voltage and stabilizes the current.
