Motorcycle Market
In many cities, urbanization has led to a rapid increase in the demand for mobility. Most of this new demand has been satisfied by the individual private transport industry, within which motorcycles have an important share: around 30% of the vehicles in the world are motorcycles. Thus, the motorcycle market has experienced an upward trend, especially in developing countries. That uncontrolled growth brings along mobility, accidents, and environment-related issues that concern policy-makers. Research trends regarding this matter evidence that greenhouse gas emissions, sustainability, environmental impact, and developing countries are the topics of greater interest for researchers. In addition, taking into account the needs of modern cities, sustainable modes of transport such as electric and shared mobility are compulsory as a priority on governments' agendas.

Basic Oxygen Furnace Slag Characteristics and Properties
Basic oxygen furnace slag is an significant environmental liability produced by the steel industry, considering the volume of material produced and its specific physical and chemical characteristics. To further understand the advantages and limitations of BOF slag aggregate and to establish its role in the replacement of natural sand in Portland cement concrete, the slag was characterized in depth in terms of both its physical and morphological properties.

El Toro Loco (Truck)
El Toro Loco (Spanish for "The Crazy Bull") is a monster truck currently racing in the Monster Jam series. It is currently driven by Kayla Blood. Other drivers of have included Dan Rodoni, Aaron Basl, Ryan Huffaker, Joey Parnell, Chris Baker, and Nathan Weenk. It features one of the first 3-D body shells, with horns sticking out of the roof. This body was originally designed for Bulldozer, and was found a second use for El Toro Loco. As El Toro Loco has increased in popularity, it has become the primary truck for the body style.

Robert Kearns
Robert William Kearns PhD (March 10, 1927 – February 9, 2005) was an American engineer, educator and inventor who invented the intermittent windshield wiper systems used on most automobiles from 1969 to the present. His first patent for the invention was filed on December 1, 1964. Kearns won one of the best known patent infringement cases against Ford Motor Company (1978–1990) and a case a

Hybrid Microgrid System
A novel energy management system for a hybrid microgrid has been developed that uses a new control algorithm termed Inefficient Power Conversion Elimination Algorithm (IPCEA). The proposed algorithm compares the Net Transferable Power (NTP) available at the DC side with the loss rate across the converter. The converter is switched off (or disconnected from the grid and load) if the NTP is less than 20% of the converter rating to avoid low-efficiency power conversion. The solar PV system is connected to the DC bus to supply the DC loads while the AC loads are supplied from the AC source (utility power). An auxiliary battery pack has been integrated to the DC side to feed DC loads during the absence of solar energy. Battery Energy Storage System (BESS) has been deployed to manage energy distribution effectively. Power distribution is managed using a centralized microgrid controller, and the load demand is met accordingly. Thereby, power generated by solar PV can be utilized effectively. Microgrid technology's effectiveness is emphasized by comparative analysis, and the achievements have been discussed in detail and highlighted using a prototype model. The proposed study intends to design a novel switching strategy to incorporate a hybrid microgrid in the distribution system effectively. It comprises the following conventional electrical installation with an intelligent microgrid distribution system: i) To implement a renewable-based IPCEA considering the availability of Net Transferable Power (NTP) at DC bus and the rate of converter loss to minimize low efficient power conversion. ii) To effectively manage battery energy within the DC side of the microgrid to minimize the charge cycle and improve its performance.  iii) To decrease the stress on the utility grid by reducing the rate of power exchange.

Waste Cooking Oil for Biofuel in India
Waste or used cooking oil (WCO/UCO) is a common source of trans fat consumed by Indians, leading to many non-communicable diseases like diabetes, hypertension, cardiovascular diseases, stroke, cancer, etc. In fact, out of 230 million MT of edible oil consumption, India is currently capable of producing only 3 million MT of biodiesel. Moreover, with the increased emphasis on the circular economy to improve rural employment opportunities, India should adopt a complete exergy analysis of biodiesel production from WCO.

Bus Scheduling with Evolutionary Optimization
In public transport operations, vehicles tend to bunch together due to the instability of passenger demand and traffic conditions. Fluctuation of the expected waiting times of passengers at bus stops due to bus bunching is perceived as service unreliability and degrades the overall quality of service. For assessing the performance of high-frequency bus services, transportation authorities monitor the daily operations via Transit Management Systems (TMS) that collect vehicle positioning information in near real-time. This work explores the potential of using Automated Vehicle Location (AVL) data from the running vehicles for generating bus schedules that improve the service reliability and conform to various regulatory constraints. The computer-aided generation of optimal bus schedules is a tedious task due to the nonlinear and multi-variable nature of the bus scheduling problem. For this reason, this work develops a two-level approach where (i) the regulatory constraints are satisfied and (ii) the waiting times of passengers are optimized with the introduction of an evolutionary algorithm. This work also discusses the experimental results from the implementation of such an approach in a bi-directional bus line operated by a major bus operator in northern Europe.

Diamond DA42
The Diamond DA42 Twin Star is a four seat, twin engine, propeller-driven airplane developed and manufactured by Austrian company Diamond Aircraft Industries. It was Diamond's first twin engine design, as well as the first new European twin-engine aircraft in its category to be developed in over 25 years. In 2004, the DA42 became the first diesel-powered fixed-wing aircraft to perform a non-stop crossing of the North Atlantic. By 2012, the DA42 had become a key revenue generator for the company, having gained popularity with government and military operators in addition to the civil market that had suffered as a result of the Great Recession. Government customers have typically employed the type in the aerial surveillance role, which contributed towards the development of the Aeronautics Defense Dominator, a medium-altitude long-endurance (MALE) unmanned aerial vehicle (UAV), which had been derived from the DA42.
