The actual effectiveness of vibration-dampening measures for the north-south high-speed rail near the Tainan Science-based Industrial Park (台南科學園區) can't be known until the railway is up and running, a National Science Council official said.
According to local media reports, the unnamed official said that while standards for the project have been based on simulations, whether or not the measures the council is proposing will meet expectations cannot be fully known until the railway is operational.
The council will publicize the details of the project, which could include building vibration-dampening trenches between the railway and high-tech manufacturing operations, the reports said. Companies interested in the project can begin submitting bids next month, according to the reports.
The railway, which is being built at a cost of NT$446 billion under a build-operate-transfer model, will link Taipei and Kaohsiung, with some other stops.

Last June, Taiwan High Speed agreed to change the design of the elevated track that runs through the park.
The council is blame for the problem since planning for the park began well after the route of the train was established. As a result, the council constructed a mock viaduct to simulate the path the train will take through the park and has run tests to evaluate what responses it can take to reduce the impact of the passing train, the reports said.
The council's mishandling of the issue was reinforced during the dispute when it urged the railway to restrict vibration levels to 36 decibels (dbs). The figure was considered to be absurd since background noise had already been measured at 48dbs at the site when it was still just a rice paddy.
A US Federal Railway Administration reported in a 1998 study that strengthening the foundations of buildings in areas nearby the railway could effectively reduce vibrations, while the placement of insulated trenches between the railway and neighboring structures could also reduce vibrations.

After several years flying high as Asia’s best Nvidia Corp proxy, Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) is increasingly vying with other artificial intelligence (AI) stocks for investor attention. Stock traders are chasing a wider array of beneficiaries as mainstream usage of AI creates demand for hardware beyond the most-advanced chips TSMC makes for Nvidia. Subthemes from the deepening memory crunch to advances in robotics are also luring bids. At the same time, investment caps on single stocks are pushing funds to diversify, while retail investors long familiar with TSMC through its US depositary receipts are being offered a broader set of
Netherlands-based semiconductor equipment supplier ASML Holding NV yesterday said that it is planning to hire an additional 1,000 people in Taiwan this year in response to growing demand from clients. ASML had previously planned to recruit 600 people this year, but that the plan has been adjusted upward, ASML vice president and ASML Taiwan general manager Grace Wang (汪佳慧) told reporters. ASML has a workforce of more than 4,500 in Taiwan, accounting for about 10 percent of its global total, Wang said. This year’s recruitment campaign would focus on adding people in the customer support, manufacturing and supply chain domains to assist ASML
UNDER MICROSCOPE: Taiwan detained three people who allegedly conspired to buy servers in Taiwan and export them using fraudulent documentation, prosecutors said Nvidia Corp chief executive officer Jensen Huang (黃仁勳) on Saturday urged Super Micro Computer Inc to tighten up on compliance after Taiwan detained three people this week for allegedly making fraudulent declarations about artificial intelligence (AI) servers made by its US partner. The development marked the nation’s first crackdown on semiconductor smuggling, which grew after the US slapped restrictions on exports of high-end chips such as Nvidia AI accelerators to China. Nvidia is “rigorous” in explaining regulations to all of its partners, Huang told reporters after arriving in Taipei. “Ultimately Super Micro has to run their own company,” he said in response to
Nvidia Corp yesterday announced that CEO Jensen Huang (黃仁勳) would attend an employee meeting in Taipei tomorrow to celebrate the launch of the company’s Taiwan headquarters project. Huang would attend a gathering at the site of Nvidia’s planned headquarters in Beitou Shilin Technology Park (北投士林科技園區), the company said in a statement. After arriving in Taiwan on Saturday last week, Huang told reporters that he plans to meet with Quanta Computer Inc (廣達) chairman Barry Lam (林百里) and Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) chairman C.C. Wei (魏哲家), and would attend the groundbreaking ceremony for Nvidia’s Taiwan headquarters tomorrow. Nvidia has not yet applied
