Abstract

The purpose of this study was to determine the characteristics of pedestrian and pedestrian traffic modeling on the interurban residential area, Makassar, Indonesia. Male pedestrians who walk without carrying goods, under 15 years of age, walk with the greatest speed, which is an average of 0.82 m/s and 0.4 m/s for the category of male pedestrians aged over 60 years. The average walking speed for women without carrying things with age less than 15 years, 15-30 years, 30-45 years, 45-60 years, and over 60 years, respectively, is 0.63 m/s , 0.55 m/sec, 0.5 m/sec, 0.47 m/sec, and 0.45 m/sec. Meanwhile, male and female pedestrians who walk with goods for each age category have an average speed of 0.8 m/s, 0.5 m/s, 0.48 m/s, 0, respectively. 44 m/sec, 0.47 m/sec, 0.42 m/sec, 0.47 m/sec, 0.38 m/sec, 0.35 m/sec, and 0.37 m/sec.

Abstract

Biomass is one of the mains means of exploiting renewable energy. The growth in heavy fuel use increases around 8% per year and the market for this fuel had a growth forecast of 40 to 50 million tons in 2020. In this scenario, the study of the different biomasses, it is necessary to show new waste for use in energy production. For the densification process, it is necessary to know about variables like pressing time, granulometry and compression force. This work aimed to characterize briquettes made from the cassava stalk biomass (Manihot esculenta Crantz). The waste was dried at 12% humidity, ground and sieved with 16 mesh e 42 mesh granulometry. It was made 24 briquettes equally divided into 12 briquettes of 16 mesh and 12 briquettes of 42 mesh. Two forces were applied........

Abstract

This paper presents the performance comparison of bare frames, fully and partial infilled frames having different infill wall thickness in a probabilistic frame work. Normally at design stage of buildings, infill walls are considered as non-load bearing walls due to more uncertainties involved in the modelling of masonry infill walls, whereas it can resist significant amount of lateral forces under seismic loads which may change the global performance of buildings. In this study exceedance probabilities and the reliability index of RC frames with two different infill wall thicknesses used in the Indian Construction practice are computed. It is found that higher thickness of infill wall is beneficial to the global performance of buildings for a fully infilled frame and detrimental for partially infilled frames......

Abstract

To make Online money transfer secure and less costly without going through any trusted third party, in 2008, one researcher called himself as 'Satoshi Nakamoto' invented cryptocurrency known as 'Bitcoin'. Satoshi Nakamoto suggested that Online money transactions can be done directly peer-to-peer without including any trusted third party and with more security and anonymity of source and destination. In this paper, we described an analysis of Satoshi Nakamoto's Bitcoin currency, proof of work, Bitcoin mining, challenges, and weaknesses of Bitcoin, and how revolutionized the Bitcoin cryptocurrency will be in future. We also de- scribed different types of possible attacks on Bitcoin Network.

Keywords: bitcoin, cryptocurrency, block chain, ledger.
