Portable Solar Street Lamp
PORTABLE SOLAR STREET LAMP ARIFFIN BIN ABDULLAH This thesis is submitted as partial fulfillment of the requirement for the award of the Bachelor Degree Electrical Engineering (Power System) Faculty of Electrical & Electronic Engineering Universiti Malaysia Pahang NOVEMBER, 2008 v ABSTRACT This system is designed for outdoor application in un-electrified remote rural areas. This system is an ideal application for campus and village street lighting. The system is provided with battery storage backup sufficient to operate the light for 10-11 hours daily. The project is about to develop and fabricate the circuit that can charge the lead acid battery during day time by using solar as the source. To control the circuit for charging, I have used the circuit charging that can implement the condition of the charging whether it’s in charging condition of in float condition. When charging condition, red LED will turn on until the battery reach the full charge state that is in floating condition and green LED will turn on. For the switching, I used PIC16F877A to switch on the lamp, by using the photocell sensor. The PIC16F877A will determine whether it is daytime or night time. The light will automatically on when the photocell sensor give the input to the PIC and PIC will give the output to the relay to switch on the light. To control the intensity of the light, we need the other input from the sensor. When sensor detect, PIC will give the output to switch on for the second light. So the intensity of the light will increase and the timing will start counter. -

CAV technologies are being developed rapidly and they are foreseen to penetrate the market at a rapid pace. On the other hand, work zones (WZs) have become common areas on highway systems as a result of the increasing construction and maintenance activities. The near future will therefore bring the coexistence of CAVs and WZs which makes their interaction inevitable. WZs expose all vehicles to a sudden and complex geometric change in the roadway environment, something that may challenge many of CAV navigation capabilities. WZs however also impose a space contraction resulting in adverse traffic impacts, something that legitimately calls for benefiting from the highly efficient CAV functions. CAVs should be able to reliably traverse WZ geometry and WZs should benefit from CAV intelligent functions. This paper reviews the state-of-the-art and the key concepts, opportunities, and challenges of deploying CAV systems at WZs. -

As road pavements age, maintenance work for safety purposes becomes critical. However, inspecting all pavement markings at the right time is very challenging due to the lack of available human resources. This study was conducted to develop an automated condition analysis framework for pavement markings using machine learning technology. The proposed framework consists of three modules: a data processing module, a pavement marking detection module, and a visibility analysis module. The framework was validated through a case study of pavement markings training data sets in the U.S. It was found that the detection model of the framework was very precise, which means most of the identified pavement markings were correctly classified. -

Cover Manual book for driver’s license test The Land Traffic Act, B.E. 2522 (1979) Assembly of Driving Schools, Thailand Translated from Thai version of a manual book for driver’s license test developed by Department of Land Transport. Introduction Everyday road accident has caused many problems including life and property damages. Based on study, most of accidents were caused by people or having improper driving behaviors. Some of people do not understand traffic rules, drive with little caution, lack of driving skills, lack of awareness in driving with safety, and lack of disciplines to follow traffic rules. To increase knowledge related to traffic rules, regulations, skills in preventing from accidents and how to use road with safety, therefore, Department of Land Transport developed a manual related to “The Land Traffic Act, B.E. 2522 (1979) and The Motor Car Act, B. E. 2522 (1979). These two manuals aimed to disseminate knowledge about traffic rule, and correct use of motor car and road to interested people who wants to take a driving test. These manuals also help readers to understand traffic rule and drive better with quality and standard ways.

Xenon Arc Lamp
INSTRUMENTAL TECHNIQUE PRESENTATION Xenon arc lamp Madhuri Jash 01/08/2015 What is Xenon arc lamp? Xenon arc lamp is a gas discharge lamp where electric power is converted into light by an arc discharge in a xenon atmosphere at high pressure. Why we use xenon here because xenon has the highest overall conversion efficiency. History of arc lamp Carbon arc lamp was the first electric light invented by Humphry Davy in the early 1800s. This was the first widely-used and commercially successful form of electric lamp. 1875 Pavel Yablochkov had developed the Yablochkov Candle which was the first reliable carbon arc lamp and was used in Paris. 1870s-1890s Elihu Thomson and E.W. Rice Jr improved many parts of the arc light system both in DC and AC power. Then xenon short-arc lamps were invented in the 1940s in Germany and introduced in 1951 by Osram. First launched in the 2 kW size and now it is upto 15 kW. Xenon arc lamp construction .There is a fused quartz envelope with thoriated tungsten electrodes. Fused quartz is the only economically feasible material currently available that can withstand the high pressure. .the tungsten electrodes are welded to strips of pure molybdenum metal or Invar alloy, which are then melted into the quartz to form the envelope seal. .Because of the very high power levels involved, large lamps are water-cooled, An O- ring seals off the tube, so that the naked electrodes do not contact the water. .In order to achieve maximum efficiency, the xenon gas inside short-arc lamps is maintained at an extremely high pressure — up to 30 atmospheres — which poses safety concerns, large xenon short-arc lamps are normally shipped in protective shields. -

Crowd-Sourced Mapping of New Feature Layer for High-Definition
sensors Article Crowd-Sourced Mapping of New Feature Layer for High-Definition Map Chansoo Kim 1 ID , Sungjin Cho 1 ID , Myoungho Sunwoo 1 ID and Kichun Jo 2,* ID 1 Department of Automotive Engineering, Hanyang University, 222 Wangsimni-ro, Seongdong-gu, Seoul 04763, Korea; [email protected] (C.K.); [email protected] (S.C.); [email protected] (M.S.) 2 Department of Smart Vehicle Engineering, Konkuk University, Seoul 05029, Korea * Correspondence: [email protected]; Tel.: +82-2-2220-0453 Received: 8 October 2018; Accepted: 22 November 2018; Published: 28 November 2018 Abstract: A High-Definition map (HD map) is a precise and detailed map composed of various landmark feature layers. The HD map is a core technology that facilitates the essential functions of intelligent vehicles. Recently, it has come to be required for the HD map to continuously add new feature layers in order to increase the performances of intelligent vehicles in more complicated environments. However, it is difficult to generate a new feature layer for the HD map, because the conventional method of generating the HD map based on several professional mapping cars has high costs in terms of time and money due to the need to re-drive on all of the public roads. In order to reduce these costs, we propose a crowd-sourced mapping process of the new feature layer for the HD map. This process is composed of two steps. First, new features in the environments are acquired from multiple intelligent vehicles. The acquired new features build each new feature layer in each intelligent vehicle using the HD map-based GraphSLAM approach, and these new feature layers are conveyed to a map cloud through a mobile network system.
