Smoke Hazards of Tall Timber Buildings with New Products
Timber buildings can now stand very tall using new products. As timber materials are expected to be easily ignitable, the fire hazard of timber is a concern. Charring of the timber surface would maintain structural stability, but would also be accompanied by smoke. Although treating timber products with fire retardants would delay the ignition time under low radiative heat flux, toxic combustion products and unburnt fuel would be emitted immediately upon burning. More smoke and higher toxic gas concentrations such as carbon monoxide would be given off upon burning some fire retardants under high flashover heat fluxes. Due to the fast upward movement of smoke under stack effect, spreading of toxic smoke in tall timber buildings would lead to a hazardous environment. Engineered timber consists of derivative timber products. New engineered timber products are manufactured with advanced technology and design, including cross-laminated-timber (CLT), laminated veneer lumber (LVL) and glue-laminated timber (Glulam). The fire behaviour of timber products has been studied for several decades. However, the smoke hazards of using new timber products in building construction should be monitored. The objective of this study is to inspire stakeholders in fire safety of timber buildings, inter alia smoke hazards, to use new timber products to build tall buildings.

Insight and Background of a Blockchain-based IoT economy
In the IoT-based economy, a large number of subjects (companies, public bodies, or private citizens) are willing to buy data or services offered by subjects that provide, operate, or host IoT devices. To support economic transactions in this setting, and to pave the way for the implementation of decentralized algorithmic governance powered by smart contracts, the adoption of the blockchain has been proposed both in scientific literature and in actual projects. The blockchain technology promises a decentralized payment system independent of (and possibly cheaper than) conventional electronic payment systems. However, there are a number of aspects that need to be considered for an effective IoT–blockchain integration.

Optical PAyload for Lasercomm Science
Optical Payload for Lasercomm Science (OPALS) is a spacecraft communication instrument developed at the Jet Propulsion Laboratory that was tested on the International Space Station (ISS) from 18 April 2014 to 17 July 2014 to demonstrate the technology for laser communications systems between spacecraft and ground stations. The purpose of OPALS is to do research into replacing traditional radio-frequency (RF) communications which are currently used on spacecraft. This will allow spacecraft to increase the rate at which data is downlinked by 10 to 100 times. It also will have less error than RF communication. It launched from Cape Canaveral Air Force Station to the ISS on 18 April 2014 on a Falcon 9 SpaceX CRS-3 Dragon capsule resupply. The experiment used commercial products rather than space qualified components.

Door-Opening Drones
Doorknob accessories, wheelchair-mounted door-opening accessories, door-opening robots, and door-opening drones—were used to group the various technologies for manually opening doors. Drones are unmanned aerial vehicles (UAVs) with a wide range of applications, including product delivery, asset inspection, search and rescue, law enforcement and military services, disaster management, and emergency medical services. Drones are emerging as safe alternatives to humans in applications involving inaccessible environments or dangerous scenarios. In cases of medical emergencies, when a person is stuck in remote locations and an ambulance is unable to reach a patient in time, medical drones are being used for emergency medical services. Door-opening drones are unmanned aerial vehicles (UAVs) equipped with the capability to open doors.

SODAR
SODAR (SOnic Detection And Ranging), also written as sodar, is a meteorological instrument used as a wind profiler to measure the scattering of sound waves by atmospheric turbulence. SODAR systems are used to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere. Sodar systems are in fact nothing more than sonar systems used in the air rather than in water; more specifically, since they operate using the Doppler effect with a multi-beam configuration to determine wind speed, they are the exact in-air equivalent to a subclass of sonar systems known as acoustic Doppler current profilers. Other names used for sodar systems include sounder, echosounder and acoustic radar.

Hand Pose Recognition Using Parallel Multi Stream CNN
Recently, several computer applications provided operating mode through pointing fingers, waving hands, and with body movement instead of a mouse, keyboard, audio, or touch input such as sign language recognition, robot control, games, appliances control, and smart surveillance. With the increase of hand-pose-based applications, new challenges in this domain have also emerged. Support vector machines and neural networks have been extensively used in this domain using conventional RGB data, which are not very effective for adequate performance.

Biophilic Design in Preschool Interiors
Modern living has made nature more and more difficult for individuals to access, but the yearning to connect with nature still exists. Children are particularly affected by this, as they have to stay indoors while separated from their parents, which is especially true for them. Biophilic design is an architectural and interior design concept that aims to bring humans closer to nature by integrating natural components into the built environment.

Shortline Railroad
A shortline railroad is a small or mid-sized railroad company that operates over a relatively short distance relative to larger, national railroad networks. The term is used primarily in the United States and Canada. In the U.S., railroads are categorized by operating revenue, and most shortline railroads fall into the Class III or Class II categorization defined by the Surface Transportation Board. Shortlines generally exist for one of three reasons: to link two industries requiring rail freight together (for example, a gypsum mine and a wall board factory, or a coal mine and a power plant); to interchange revenue traffic with other, usually larger, railroads; or to operate a tourist passenger train service. Often, short lines exist for all three of these reasons.
