Abstract:

Advances in laser physics and its applications have triggered the proposition and development of Laser Astrodynamics. In carrying out research projects on Laser Space Programs, it is necessary to process the laser signal sent back from remote spacecraft. After traveling an extremely long distance, the power of this signal is greatly reduced. Weak-light phase-locking is the key technique used for signal amplification in these space projects. After the returning laser beam is collected by telescope, it is used to phase-lock a local laser oscillator. The local laser then carries the phase informa

Abstract: People nowadays don't have much time to sit in a cafeteria and wait for the server to take their order. Many customers come to the canteen during their lunch break or recess, so they only have a little time to eat before returning to their offices or institutions. As a result, this programme allows users to save time and order meals anytime they want without having to contact the waiter again. Paperwork is included in the manual system in the form of keeping multiple files and manuals. Maintaining vital data in files and manuals is a risky and time-consuming operation. The project ex

In the area around PPYD Al Ikhlas Singosari, Malang, there is a river with a fast enough flow that can be used as a hydroelectric power plant as estimated. After investigation, it was found that the potential electrical power that could be generated was 1,118.56 Watts so it was classified as a pico hydro power plant. Therefore, in this research, one of the main parts of the pico hydro power plant, namely the turbine, was designed. The type of turbine designed is a crossflow turbine with an outer diameter of 75 cm and an inner diameter of 3 cm, the width of the runner blades is 40 cm, the dista

As an alternative energy, the potential of wind power in Indonesia is quite high. Some of the constraints of wind power include the presence of intermittent winds, the average wind speed in the Indonesian is relatively low, or only certain areas that have moderate to high wind speeds, so that winds that are not too tight can cause the turbines not spinning. This study is about modifying a two pole single phase induction motor as a wind pico generator.

However, no study has addressed this issue in African countries.

Interest in very small-scale hydropower generation has increased over the past few years. These pico-hydro systems range from a few watts to several kW. The exploitation of low head sites does not require expensive civil works and is environmentally sustainable. Pico-hydro systems are attractive not only for remote areas where the grid is not available, but also for grid connection. This is especially relevant in existing infrastructures, used for other activities but which can also be used for energy generation. Waterwheels are emerging with enormous potential in this context.

INTRODUCTION Published data suggest that the 2-week wait system and triple assessment at one fast-track clinic visit is an out-dated method of capturing disease from a referral population. These studies report up to 32% of breast cancer coming from routine referrals. It has been recommended, therefore, that all breast referrals should be seen within 2 weeks. The sheer volume of referrals are likely to prevent this target being achieved. The aim of this study was to analyse the performance of our fast-track system.
