Financial Viability. Examiners have recommended that a few nations may have over-extended their HSR systems, claiming that incomes and benefit edges have fallen, and cheap flights and car-sharing administrations may draw a few clients absent from rail choices. The actualities, be that as it may, appear to give a false representation of these notices. In China, HSR lines have demonstrated their productivity, and all through Asia and Europe, HSR is giving a lower fetched and shorter travel time elective to...

High Speed Rail (HSR) may be a sort of rail transport that runs essentially quicker than conventional rail activity, utilizing an coordinates framework of specialized rolling stock and committed tracks. Whereas there’s no single standard that applies around the world, modern lines in overabundance of 250 kilometers per hour (160 mph) and existing lines in abundance of 200 kilometers per hour (120 mph) are broadly considered to be high-speed. The to begin with high-speed rail framework, the TĹkaidĹ Shinkansen started...

Technology: Persistent welded rail is for the most part utilized to decrease track vibrations and misalignment. Nearly all high-speed lines are electrically driven by means of overhead cables, have in-cab flagging, and utilize progressed switches utilizing exceptionally moo section and frog angles. Road-rail parallel layout: Road Rail Parallel Format employments arrive adjacent to interstates for railroad lines. Illustrations incorporate Paris/Lyon and KĂślnâFrankfurt in which 15% and 70% of the track runs close to thruways, separately. Track sharing: In China, high-speed...

Network Speed 1. Abstract There are typically two aspects to a network: the wide area network (WAN) and the local area network (LAN). The WAN side of the network is delivered by a telecommunications company (telco) or an Internet Service Provider (ISP) and typically consists of a physical link from the telcoâs infrastructure in the street to the userâs premises. The physical link may consist of twisted-pair copper, co-axial cable, optical fibre, or it may be wireless in the form...

Nearly 1.25 million people die in road crashes each year around the glove, on average 3,287 deaths a day. An additional 20-50 million are injured or disabled. Road traffic crashes rank as the 9th leading cause of death and account for 2.2% of all deaths globally. If the government implements a removal of the speed limit of motorway, the safe and security of our citizens will be at risk, not to mention is indirect negative effects on the British economy....

Abstract Road accidents are the serious humanity and public health issue in Metro Manila. The problem is increasing day by day. Apart from the loss of many lives, the effect of the road crashes on the countryâs economy is massive. In Metro Manila, human factors are the main contribution of major road crashes while over-speeding is one of the accelerating factors to the increase of road casualties. Existing measures to limit these problems have been unsuccessful to diminish the road...

âSpeed is the essence of war. Take advantage of the enemyâs unpreparedness, travel by unexpected routes and strike him where he has no precautions.â (Sun & Griffith,1964) In a war, speed is the key that leads us toward victory. Alibaba group effectively apply the speed strategy to their daily business operations. Alibaba invests in AI (artificial intelligence) technologies since few years ago to speed up some trivial process for example quality and quantity control, classification of goods and so on....

In this twenty-first century and modern society, the number accident and crashes have been biggest concern due to the increase in transportation system and changes in speed limits. Speed limits have been implemented in the US since 1861 and it has resulted in minimizing accidents so far. But, as like all, they need to be updated whenever required and this essay discusses on the reasons why this is the right time to have changes in the speed at which vehicles...

Rational The claim, âEvery K over is a killer has several aspects that could be investigated. The claim implies that driving an excessive amount over the regulated speed limit is dangerous and could cause possible death. The first aspect that can be investigated is what speed limits are and how speed limits are appropriately chosen for different areas and driving conditions. The research found that speed limits are set to improve safety by reducing the probability and severity of a...

1. Introduction As a fundamental constant, the exact value of the speed of light has been disputed for centuries. The measurement of the speed of light brought arise to new areas of Physics such as Einsteinâs Theory of Relativity. This Theory of Relativity was based entirely on the relativistic effects caused by objects moving near the speed of light. This brought arise to an exclusively new area of Physics, furthermore it is no wonder why the velocity of light in...

Introduction Newton’s three laws of motion for several decades remained a matter of course. Until 1905, the physicist Einstein published a paper questioning the accuracy of these laws, which are now known as the Special Theory of Relativity, followed by the General Theory of Relativity, Its lack of understanding, where this understanding was based primarily on Newton’s law of gravity. The theory of relativity states that the laws of physics do not change and are the same everywhere. The theory...

Introduction: This report investigates the effect of wheels on the speed of a solar car. This is achieved by considering the effects of force and energy transformation and what happens if extra wheels are added. Force is the act of pushing or pulling on an object with mass that causes it to change velocity (e.g.: accelerating a car). Force is also a vector which means it has both magnitude and direction. Energy transformation aka energy conversion is the act of...

Albert Einstein was born March 14, 1879, in Germany and was a physicist who developed the special and general theories of relativity, considered to be his most famous piece of work. His research spanned from quantum mechanics to theories about gravity and motion. After publishing some papers that changed how the world knew space, time and gravity, he toured the world giving speeches about his discoveries. Since a very young age, Einstein was extremely interested in science and was influenced...

Abstract Many people are getting killed in road accidents daily and it has become one of the major concerns for the whole world. According to WHO about 1.25 million people die in road crashes each year, on average 3,287 deaths a day and an additional 20-50 million are injured or disabled. The motivation behind this work is an attempt to make an Arduino based IOT system for real-time monitoring of speed and which aware people about the speed of the...

If someone would have told us, more than 70 years ago, that could travel faster than the speed of sound, weâd nod our heads in disbelief and laugh. I mean, think about it. – Breaking the sound barrier is as mind-boggling as supermanâs ability to defy gravity. But what if I told you, that a man achieved the impossible right before the 1950s? So, who is this guy? How did he manage to travel faster than the speed of sound?...

Air we breathe in consists of molecules. Even the tiniest of regions of air will contain millions and millions of molecules. These molecules are in constant motion, traveling randomly and at great speed. There is a constant bombardment with each other and every other object that is in contact with the air. One interesting thing about air is that it is a medium through which heat or sound travels. But our current main attention will be on sound. Sound is...

The topic of kinematics in general, is an interesting topic for learning about and understanding since it includes a variety of subtopics that can be integrated through physics. This research topic can help people predict the motion of an object depending on the surface it rolls on, its density, its shape, its mass, and its volume. It interested me to find out/explore the wide perspective in predictions that come up when researching about kinematics of any rolling object, and how...
