This study aims to determine how much electric power can be generated from methane gas obtained from organic waste and how much electrical energy has not been utilized from the potential methane gas produced and how much volume of pyrolysis oil is produced from plastic waste produced by the people of the City. Kendari. To obtain the electrical energy produced, the volume of waste is first calculated so that the potential for waste (Q), Biogas Production Volume (VBS), and Methane Gas Volume (VGM) can be obtained. Referring to Kadir's research, 2012, the volume of pyrolysis oil produced by Kendari City is obtained. The results showed that the energy produced from the Puuwatu TPA in a daily average was 288,466,5332 kWh. While the energy flowing through the Mandirin Energi area is 125 houses and each house with a power of 450 VA (MCB 2 Ampere), the daily count used to fulfill the energy independent area is 1,080 kWh, so that energy has not been utilized from its potential. in Puuwatu TPA is 287,386.5332 kWh. While the production of plastic waste in Kendari City per year is 792 tons, the average plastic waste produced in 500 grams is 423.25 ml of pyrolysis oil or the equivalent of 1000 grams produces pyrolysis oil of 845.6 milliliters, so the amount of plastic waste in Kendari City per year year it can produce pyrolysis oil of 670 428 000 liters. Keywords: Organic Waste, Methane Gas, Electrical Energy, Pyrolysis Oil, Plastric Waste.
本研究旨在确定从有机废物中获得的甲烷气可以产生多少电力，从产生的潜在甲烷气中未利用的电能有多少，以及从城市居民产生的塑料废物中产生了多少体积的热解油。Kendari。为了得到产生的电能，首先计算废弃物的体积，从而得到废弃物的势能Q (potential waste)、沼气产量VBS (Biogas Production volume)和沼气体积VGM (Methane Gas volume)。参考Kadir的研究，2012，得到了Kendari City的裂解油产量。结果表明，普瓦图TPA日平均发电量为288,466,5332 kWh。虽然流经Mandirin Energi区域的能源是125户家庭，每户家庭的功率为450伏安(MCB 2安培)，但用于实现能源独立区域的每日数量为1,080千瓦时，因此能源没有从其潜力中得到利用。Puuwatu的TPA为287,386.5332千瓦时。而肯达里市每年产生的塑料垃圾为792吨，平均每500克产生的塑料垃圾为423.25毫升热解油或相当于1000克产生的热解油为845.6毫升，因此肯达里市每年产生的塑料垃圾量每年可产生热解油67042.8万升。关键词:有机废弃物，沼气，电能，热解油，塑料废弃物

In recent days, requirement of high spatial resolution remote sensing data in various fields has increased tremendously. High resolution satellite remote sensing data is obtained with long focal length optical systems and low altitude. As fabrication of high-resolution optical system and accommodating on the satellite is a challenging task, various alternate methods are being explored to get high resolution imageries. Alternately the high-resolution data can be obtained from super resolution techniques. The super resolution technique uses single or multiple low-resolution mis-registered data sets to generate high resolution data set. Various algorithms are employed in super resolution technique to derive high spatial resolution. In this paper we have compared two methods namely overlapping and interleaving methods and their capability in generating high resolution data are presented.

Many European countries with shores to the Mediterranean are under earthquake risk. Earthquakes in Turkey in the last 50 years caused lost of more than 50,000 human lives. Reinforced concrete buildings can collapse and cause loss of life even in earthquakes smaller than the design earthquakes defined by the seismic code. In this study, housing construction system and earthquake-resistant buildings in terms of system production problems in Turkey were discussed. The most common damage types after earthquakes are summarized.

The aim of the study was to analyze the dynamic response along an aluminum cantilever beam. The data measured were displacement (mm), velocity (mm / s), and acceleration (m/s 2 ) with 3 measurement positions on the cantilever beam. The 6061 series aluminum beam being used have length of 80 cm, height of 32 cm, and width of 32 cm. The data were collected experimentally using a vibration meter to measure beam vibrations at the various positions from the cantilever beam at a distance from support: 10 cm, 35 cm, and 60 cm, respectively. The results of the analysis showed that the values of the displacement, velocity and acceleration of the object vibrations change when the measuring point was far from the cantilever support. The maximum displacement value is 0.02 mm at 60 cm from the support, and the lowest value is 0.12 mm at 10 cm. The velocity value also increases, maximum value is 38.58 mm/s at 60 cm from the support, and the minimum value is 12.30 mm/s at 10 cm from the support. Accordingly, the acceleration value is maximum at 60 cm from the support: 91150 mm/s 2 and the minimum at 10 cm: 66900 mm/s 2 .

Abstract: The objective of this paper is to present an effective new methodology to optimize the maintenance costs of bridges stock. Optimization takes place at the network level and not in a project level (bridge by bridge). The dynamics of passage between bridges condition state (from 1 to 5) is achieved by the Markov chains probabilistic method. The Markov transition matrix is determined either by ratios of total areas and areas degraded annually, or by the resolution of an optimization problem. In the latter case, the nonlinear optimization algorithm SQP (Sequanciel Quadratic Programming) is developed. A bridge maintenance matrix is introduced in the calculation of the repair cost. The originality of our approach is to parameterize this matrix by introducing the different optimization variables of the problem. Finally, the cost function to be optimized annually is calculated and optimized by a genetic algorithm. This cost function represents the cost of maintaining the entire asset.
