Disclosed is a system and method for decreasing airflow and improving ventilation within a tunnel, such as a railroad tunnel, including a path for movement of a vehicle (e.g., train) therethrough. The system has a plurality of air baffles mounted within the tunnel, each device comprising a body and a mounting device. Each mounting device positions each body inside and along the length of the tunnel between the entrance and the exit. The air baffles are configured to restrict airflow at least in part in a longitudinal direction of the tunnel, thereby increasing a relative difference between a vehicle speed and air speed in a tunnel annulus when the vehicle passes through the tunnel. The restriction (e.g., decrease) of airflow in the tunnel reduces the piston effect resulting from the vehicle or train passing through, thus reducing emissions and heat generated by the locomotives in the tunnel.

An embedded controller is provided for a computer, including a processor, first one or more logic elements providing a serial peripheral interface (SPI) module to communicatively couple the embedded controller to an SPI bus as an SPI slave, and second one or more logic elements providing a platform environment control interface (PECI)-over-SPI engine, to build an SPI packet providing an encapsulated PECI command and send a notification to an SPI master that the packet is available.

A solar drying tunnel having a low-profile and which is transportable includes a bottom portion, a frame, a cover, and externally controlled rolling mechanism for turning grain over. The tunnel may also include a fan at one end and a chimney at another end to provide enhanced air flow.

Embodiments are directed to an electromagnetic memory device having a memory cell and an encapsulation layer formed over the memory cell. The memory cell may include a magnetic tunnel junction (MTJ), and the encapsulation layer may be formed from a layer of hydrogenated amorphous silicon. Amorphous silicon improves the coercivity of the MTJ but by itself is conductive. Adding hydrogen to amorphous silicon passivates dangling bonds of the amorphous silicon, thereby reducing the ability of the resulting hydrogenated amorphous silicon layer to provide a parasitic current path to the MTJ. The hydrogenated amorphous silicon layer may be formed using a plasma-enhanced chemical vapor deposition, which can be tuned to enable a hydrogen level of approximately 10 to approximately 20 percent. By keeping subsequent processing operations at or below about 400 Celsius, the resulting layer of hydrogenated amorphous silicon can maintain its hydrogen level of approximately 10 to 20 percent.

A major difficulty of solving continuous POMDPs is to infer the multi-modal distribution of the unobserved true states and to make the planning algorithm dependent on the perceived uncertainty. We cast POMDP filtering and planning problems as two closely related Sequential Monte Carlo (SMC) processes, one over the real states and the other over the future optimal trajectories, and combine the merits of these two parts in a new model named the DualSMC network. In particular, we first introduce an adversarial particle filter that leverages the adversarial relationship between its internal components. Based on the filtering results, we then propose a planning algorithm that extends the previous SMC planning approach [Piche et al., 2018] to continuous POMDPs with an uncertainty-dependent policy. Crucially, not only can DualSMC handle complex observations such as image input but also it remains highly interpretable. It is shown to be effective in three continuous POMDP domains: the floor positioning domain, the 3D light-dark navigation domain, and a modified Reacher domain.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

The decline or drying up of groundwater sources near a tunnel route is damaging to groundwater users. Therefore, forecasting the impact of a tunnel on nearby groundwater sources is a challenging task in tunnel design. In this study, numerical and analytical approaches were applied to the Qomroud water conveyance tunnel (located in Lorestan province, Iran) to assess the impact of tunnelling on the nearby extraction water wells. Using simulation of groundwater-level fluctuation owing to tunnelling, the drawdown at the well locations was determined. From the drawdowns and using Dupuit's equation, the depletion of well flow rates after tunnelling was estimated. To evaluate the results, observed well flow rates before and after tunnelling were compared with the predicted flow rates. The observed and estimated water well flows (before and after tunnelling) showed a regression factor of 0.64, pointing to satisfactory results

In a first, the Central Railway (CR) seems to have come up with a permanent solution for the falling boulders in the ghat section known for disrupting services during monsoon. Accordingly, CR has recreated steel tunnels which will trap falling boulders and protect the passing trains below.

Last year, CR deployed 60 additional CCTV cameras, posted gangmen, rock-bolting at 750m stretch and drone cameras to alert approaching trains, but all were of limited help.In 2017, three passengers on the Hubli-Lokmanya Tilak Terminus (LTT) Express suffered injuries after a boulder came crashing through the roof while it was passing through Khandala ghat.

After the problem was analysed last year, it was revealed that the increased incidents of boulders falling on tracks along with mud had been due to heavy monsoon.

So, officials started working on the steel tunnel portal extension last year in four tunnels. "The work has been progressing with the lockdown in place and will be completed before the monsoon sets in," CR chief public relations officer Shivaji Sutar said. "Work of removing loose boulders is still underway and at present, we are running boulder special trains, and patrolling the mountains to scan loose boulders and tunnels," he added.

In the history books
Historically, the Indian Railways has been dealing with the problem of boulders in this stretch since its inception. But they never cancelled these many trains to manage the situation as they have done in recent years. The archival records of the Great Indian Peninsula Railway, which is now called Central Railway, on the initiation of passenger rail service on the ghat section in 1864, had issued a notice on the operation of the 'terrain section' by dividing the entire stretch into 13 parts with three watchmen deputed for each.

The Maharashtra Metro Rail Corporation (Maha-Metro) found two mysterious tunnels on March 26 at Swargate in Pune while carrying out its underground work for laying the metro rail line. On Thursday, it was revealed that the tunnel is more than a century old and was built by the Britishers for water management. The spot was inspected and two channels were found to be 57 metres in length, six feet in height and closed at both ends. It was assumed that the tunnels must have been a water treatment plant built by the British governing agencies.

After the tunnels were discovered, the Archaeological Survey of India (ASI) along with a historical expert visited the site due to which the work was stopped for some time. However after a through references of the documents and thesis from the government, the ASI has given no objection notice.

Vilas Vahane, the assistant Director of ASI told mid-day, "Our team inspected the site and discovered the Regional Plan for Pune Metropolitan Region document which consisted references of the tunnels by the Pune Metropolitan regional planning board. The tunnels belong to the British era between 1908 to 1915 and are around 109 years old. Such a reference is found in Chapter VIII of the book of the Public Utility Service on water supply."

The PRO of Maha-Metro said that they have received a NOC regarding the construction and the work has not been affected.
