H-BIM Workflow for Interventions on Heritage Building Elements
Intervention projects for heritage buildings depend on the quality of multidisciplinary data sets; their collection, structure, and semantics. Building information model (BIM) based workflows for heritage buildings accumulate some of the data sets in a shared information model that contains the building’s geometry assemblies with associated attributes (such as material). A BIM model of any building can be a source of data for different engineering assessments, for example, solar and wind exposure and seismic vulnerability, but for historic buildings it is particularly important for interventions like conservation, rehabilitation, and improvements such as refurbishment and retrofitting. Semantic technologies, such as ontologies, enhance the quality of information on interventions in historical buildings.

H. Lane Mitchell
Henry Lane Mitchell, known as H. Lane Mitchell (August 17, 1895 – November 8, 1978), was a civil engineer who served from 1934 to 1968 as the elected citywide public works commissioner in his adopted city of Shreveport, Louisiana. Hailed during his tenure as a popular success, his life after retirement was marred by legal troubles which led to his imprisonment upon conviction of theft of multi

H2S Removal from Gas Mixtures Using Zeolites
Natural gas, biogas, and refinery gas all include H2S, which has adverse effects not only on the environment and human health but also on the equipment and catalysts that are employed in the relevant processes. H2S is removed from the aforementioned gases using a variety of techniques in order to fulfill the necessary sales criteria and for reasons of safety. The adsorption method stands out among various other approaches due to its straightforward operation, high level of efficiency, and low overall cost. This technique makes use of a variety of adsorbents, such as metal-organic frameworks (MOFs), activated carbon, and zeolites. The use of zeolite-based adsorbents is by far the most common of these various types.

Halide Perovskite Materials for Solar Cells
The nomenclature “perovskite” was assigned to this structure in honor of Lev Perovski, the Russian mineralogist who initially unveiled it; since then, the name “perovskites” has been used to describe all materials that share calcium titanate’s crystal structure. The general formula for the perovskite light absorption layer is ABX3, where A is an organic cation (CH3NH3+), B is a metal cation (Pb2+), and X is a halide anion (I−).

Halide Perovskites
Halide perovskites (HPs), with an excellent photoactive nature, dielectric, piezoelectric, ferroelectric, and pyroelectric properties, have been potential candidates for obtaining flexible nanogenerator-based self-powered sensors including light, pressure, and temperature. Additionally, the photo-stimulated dielectric, piezoelectric, and triboelectric properties of HPs make them efficient entrants for developing bimodal and multimode sensors to sense multi-physical signals individually or simultaneously.

Hamburger Flugzeugbau HFB 320 Hansa Jet
The HFB 320 Hansa Jet is a twin-engine, ten-seat business jet that was designed and produced by Germany aircraft manufacturer Hamburger Flugzeugbau between 1964 and 1973. The most recognisable and unconventional feature of the aircraft is its forward-swept wing. The Hansa Jet begun development during the 1960s, the selection of the forward-swept wing can be largely attributed to head engineer Hans Wocke, who had previously worked on the experimental Junkers Ju 287. It possessed a spacious cabin, which was achieved due to its wing design, but was a relatively heavy aircraft, posing some issues during both take-off and landing. On 21 April 1964, the prototype conducted its maiden flight. On 12 May 1965, the first prototype was lost during a test flight, killing Hamburger Flugzeugbau's chief test pilot; several design changes were made to change the Hansa Jet's stall characteristics. Type certification of the Hansa Jet was received during early 1967 and the first deliveries commenced during the following year. The largest customer of the type was the German Air Force , who tasked it with both training and VIP transport duties. During 1973, it was decided to end production of the Hansa Jet. Reasons for the programme's termination include increased competition from newer executive jets, a decline in the value of the US dollar, and the limited sales of the type. The German Air Force continued to operate their Hansa Jets into the early 1990s. A limited number continued to be used amongst civilian operators into the 21st century.

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.

Handbike for Daily Use, Sport, and Rehabilitation Purposes
With respect to alternative devices like traditional wheelchairs, handbikes can offer advantages from biomechanical and physiological perspectives, to several kinds of users. Assuring high mechanical efficiency and homogeneous force distributions along cycles, and being suitable for indoor and outdoor activities, these systems are used for rehabilitation, sports, and daily applications. From a technical perspective, their main characteristics can vary with the device final purpose and operational context.

Handover Management for Drone Networks
The drone, also known as an Unmanned Aerial Vehicle (UAV), is an autonomously flying aircraft controlled by an individual. The terms drone and UAV are used interchangeably here. Drones have attracted extensive attention for their environmental, civil, and military applications. Because of their low cost and flexibility in deployment, drones with communication capabilities are expected to play key important roles in Fifth Generation (5G), Sixth Generation (6G) mobile networks, and beyond. 6G and 5G are intended to be a full-coverage network capable of providing ubiquitous connections for space, air, ground, and underwater applications.
