Two samples of manganese oxide nanoparticles (NPs) were synthesized by a simple solution-combustion method at ignited temperature 250 0C (C250) and 300 0C (C300). The structural and optical properties have been characterized by Xray diffraction (XRD), Fourier transform infrared spectrum (FTIR), UV-Vis absorption and Photo-luminescence (PL) spectroscopy. The XRD patterns of C300 showed a tetragonal hausmannite structure of Mn3O4 NPs, where the XRD patterns of C250 revealed a mix phase structure of the manganese oxides NPs. The obtained PL emission illustrated two broad bands. The obtained FT-IR results coincided with the XRD results. The calculated average crystallite size (D) was 27 and 26 nm for C250 and C300, respectively. The electrochemical performance of the prepared electrodes based on the synthesized samples C250 and C300 were examined in 1 M NaSO4 electrolyte solution using cyclic voltammetry. The examined electrodes based on sample C250 presented a relatively large specific capacitance 128 F.g−1. As a result, manganese oxide NPs could be a promising candidate to be used as an electrode material for supercapacitors.
采用简单的溶液燃烧法，在250℃(C250)和300℃(C300)的点燃温度下合成了两种氧化锰纳米颗粒(NPs)。采用x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、紫外可见吸收光谱(UV-Vis)和光发光光谱(PL)对其结构和光学性质进行了表征。C300的XRD谱图显示为Mn3O4 NPs的四方hausmanite结构，C250的XRD谱图显示为锰氧化物NPs的混合相结构。得到的PL发射具有两个宽频带。所得FT-IR结果与XRD结果吻合。C250和C300的平均晶粒尺寸(D)分别为27 nm和26 nm。以合成的C250和C300为基础，用循环伏安法在1 M NaSO4电解质溶液中测试了制备的电极的电化学性能。基于样品C250的电极具有较大的比电容128 F.g−1。因此，氧化锰NPs可能是用作超级电容器电极材料的有希望的候选者。

Envelope of buildings plays a major role in achieving net zero energy for existing buildings, through reducing energy demand. Providing shading on a building envelope is considered a basic strategy to minimize energy usage, especially in hot climates. This facilitates reducing solar energy that may arrive to internal spaces and increase the required cooling load. However, shading devices may block the desirable solar radiation in winter and cause an extra heating load. This study aims to identify the Net Zero energy retrofit shading strategies that could be applied on the existing multistorey residential buildings in Gaza to minimize the annual heating and cooling loads. In order to achieve this aim, the study based on an analytical method by using DesignBuilder V5 computer program, as a simulation tool. The outcomes showed that low shading coefficient for fenestration systems with mixed mode ventilation is preferable to achieve low energy consumption of buildings. In addition, the shading coefficient value that ranges between 0.7-0.5 was approved to be effective in minimizing energy consumption.

In order to reduce the significant energy consumption due to public lighting, highly efficient lighting systems using Light Emitting Diode (LED) technology have been implemented. In addition, the integration of photovoltaic solar energy into these lighting systems allows an autonomous electricity supply. This paper is intended mainly to size a photovoltaic LED street lighting system. The electrical characteristics of the different components of the system are determined. With the aid of PVsyst software, a sizing adapted for Algiers city’s meteorology is proposed for several photovoltaic technologies.

Inverters are used widely nowadays because of the increasing availability of many of renewable energy sources. Not only energy sources like solar panels but also storage banks like batteries provide DC voltage. Traditional DC-AC inverters have main limitation; its output voltage value is limited to DC-rail voltage and cannot exceed it. To overcome this limitation and to avoid the usage of transformer for boosting; in this paper brief Z-source network technique in inverters is explained. This technique can work buck/boost and inverting in one stage without need to boost DC, invert DC and finally boost AC with transformer. Quasi-Z-Source network was developed, to operate better technique than Z-Source inverter by reducing component rating, quantity and voltage stress and simplifying control strategies. Fuzzy Logic control is used as a controller for the inverter. This paper uses Mamdani method with 3 VDC, IDC and Vc1 input and 2 outputs M and Do. The designed inverter in this paper could keep the output voltage 208v AC rms 60 Hz with wide range of variable DC input (200-400) v DC.

The purpose of this paper is to investigate efficiency variation of harvesting solar energy in two completely different regions in climate, Gaza Strip, Palestine which is a sun-rich area, and Montreal, Canada which is a very cold area, especially in the winter. There are two main different ways for benefiting from solar energy. The first and the most common way is through a photovoltaic (PV) solar system that converts solar radiation into electricity. The other way is through solar thermal conversion. For sun-enriched regions, the solar thermal solution might be a very practical one at the residential level. In both ways, their use leads to reduce the consumption of fossil fuels for energy generation and thus it reduces the proportion of harmful gases such as Carbon dioxide (CO2) emissions. The comparison is carried out focusing on solar thermal collector and PV systems. Results have shown the superiority of the solar thermal collector over PV based system in hot climates while in cold one both efficiencies become comparable to each other.

In a time of catastrophes like war or earthquake, people forced to leave their houses and live in tents or remote areas. In both cases, utilities such as electricity, hot water, and probably toilet need to be provided urgently. Maker movement creates a creativity on the mind of engineers. Engineers use knowledge, which they learned to create valuable objects. In this work, a movable toilet, which can be placed in the needed region, is tailored. In this toilet, proper light and hot water are provided from solar energy. The toilet body is made from used plastic containers (1m3). In Gaza, the containers, which are used, are available at cheap prices. They are usually used to hold chlorine gallons. One small solar panel is used to provide the light to the toilet. Hot water is supplied to the toilet by small water heaters tanks that depends on small mirrors to collect the sun light. More explanation on each part will be given in details in the body of the paper.

Daily power outage lasting several hours is common in Gaza Strip. For this reason, Nasser Hospital located in the south of Gaza Strip has been using diesel generators to ensure a reliable power supply for their services and had no choice but to accept the high operating expenses resulting from the fuel consumption. Solar photovoltaic (PV) systems are proposed to be indeed a highly promising solution as a result of its drastic reduction in cost and climate characteristics. In order to reduce the fuel and logistics costs, it has been decided to invest in a PV hybrid diesel system in order to meet up with the energy demand. This paper investigates the techno-economic possibilities of the integration of photovoltaic solar with the existing diesel generators at Nasser Hospital. HOMER software has been implemented to model the new system so as to study the techno-economic and environmental performance. The simulation shows that the new system will not only cause operating cost reduction but also rapidly curb toxic emissions and environmental pollutions.

Conventional methods of traffic light systems are unable to deal with the ongoing issues surrounding congestion. The current traffic light models are not suited to tackle problems such as traffic jams, ease of access for emergency vehicles and prevention of accidents. In order to counteract these issues, we propose the 'Smart traffic light control system'.The adopted Traffic Light Controllers (TLC) in Gaza, are based on microcontroller and microprocessor. These TLCs have limitations because they use the pre-defined hardware, which is functioning according to the program that does not have the flexibility of modification on real time basis. Due to the fixed time intervals of green, orange and red signals the waiting time is more and car uses more fuel.The intended project will focus on two aspects of implementation. First and foremost, to make traffic light controlling more efficient, image processing alongside with embedded system, will be used. This system will intelligently decide when to alternate signals based on the total traffic on each road detected by cameras on each lane which will increase road capacity and traffic flow.Secondly, the minor component consists of the ability to control the traffic signals by an android application throughout the Bluetooth and wireless connection. This will be controlled by the traffic warden or police officer.The prototype of the system has been built and tested. The model is better than the current system which is limited to the Fixed Mode Traffic Light Controller. It is observed that the proposed smart Traffic Light Controller is more efficient than the conventional controller in respect of less waiting time, more distance travelled by average vehicles and efficient operation during emergency mode.

Orthogonal frequency-division multiplexing (OFDM) systems suffer from significant out-of-band (OOB) radiation. All existing techniques have several drawbacks as wasting spectral or time resources. Time domain windowing is a well-known technique where an extended smoothing window is multiplied by the modulated signal. This window reduces the signal spectrum sidelobes, however, it extends the resource Block (RB) length resulting in reduces the system data rate. In this work, we intend to review some outstanding techniques for OOB reduction, and investigate a new method of time-domain windowing that does not require extension of time-domain signal. Simulation results show that the non-overlapping windowing exhibits better peak to sidelobe ratio compared to overlapping windowing, yet at the expense of degradation of the BER versus SNR.
