Chrysler Minivan (AS)
The second-generation Chrysler minivans are a series of minivans that were manufactured and marketed by Chrysler Corporation in North America and Europe from 1991 to 1995. Officially designated the AS platform by Chrysler, the second-generation minivans were again sold in passenger and cargo configurations by the Chrysler, Plymouth, and Dodge divisions. Launched in late 1990 for the 1991 model year, the second-generation minivans were an extensive revision of the first-generation chassis and body. The model range became the first minivans offered with driver-side airbags (1991) and with optional integrated child safety seats (1992). While adding all-wheel drive as an option for the first time, the AS platform would also mark the last offering of a manual transmission. As with its predecessor, Chrysler assembled second-generation minivans at Windsor Assembly in Windsor, Ontario, Canada, with additional production at Saint Louis (North) Assembly in Fenton, Missouri from 1990 to 1994. In 1992, to supplement exports from the United States, the Chrysler Voyager began production in Graz, Austria (in the Eurostar joint venture factory between Chrysler and Steyr-Daimler-Puch). For the 1996 model year, the AS-generation minivans were replaced by the NS platform, marking the first complete redesign of the Chrysler minivans since their introduction.

Laser Dynamic Compression in Diamond Anvil Cells
The field of high-pressure materials research has grown steadily, with many remarkable discoveries having been made. Recent progress in laser material processing within diamond anvil cells (L-DACs); researchers focus on the practice of laser-driven dynamic compression within diamond anvil cells (i.e., LDC–DAC experimentation).

Alkaline–Surfactant–Polymer Flooding Mechanisms
Chemical flooding, expecially  alkali–surfactant–polymer (ASP) injection plays an important role in enhancing oil recovery under many synergetic mechanisms, in which there are four main mechanisms that have been widely used, including improving the mobility ratio between the heavy oil and the displacing phase, lowering the interfacial tension between oil and water (IFT), altering the rock wettability (oil-wet to water-wet) and emulsifying oil and water. Laboratory tests and pilot trials of ASP injection showed that the oil recovery of the emulsified system is 5% more than the cases where no emulsions existed.

Industry 4.0 and Lean Six Sigma Integration
In recent years, Industry 4.0 (I4.0) has been a recurrent theme in the literature on Lean Six Sigma (LSS), given the synergies that can arise from their combination. However, several factors can affect the integration of I4.0 and LSS in practice. This article presents a systematic literature review of the barriers to integration and the critical success factors (i.e., enablers) involved in this process.

Hydraulics
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuaries and seas. Its sub-field open-channel flow studies the flow in open channels. The word "hydraulics" originates from the Greek word ὑδραυλικός (hydraulikos) which in turn originates from ὕδωρ (hydor, Greek for water) and αὐλός (aulos, meaning pipe).

Pocket-Sized Computer
Pocket-sized computer describes the post-programmable calculator / pre-smartphone pocket-sized portable-office hardware devices that included the earlier DOS-based palmtops and subsequent Windows-CE handhelds, as well as a few other terms, primarily covering the 1980s through 2007. Sometimes called Pocket-sized computing devices, they were a series of internally different devices, and included Handheld ("Pocket-sized handheld computing device"), and the earlier-introduced Palmtop ("Pocket-sized palmtop computing device") and "pocket-sized palmtop computer." The New York Times used the term "palmtop/handheld." The media called "the first computer that fits in your palm and weighs less than a pound" and its early day competitors a palmtop. Although the word "handheld" was used before Microsoft's 1996 introduction of Windows CE, a lawsuit by Palm, Inc pushed Microsoft's use of the new term Handheld PC. By 2007, the iPhone began to replace prior portable office devices, and by a decade later there were indications that "SmartGlasses" might be their replacement.

Solar-Powered Plant Protection Equipment
Solar photovoltaic (PV) devices present a positive approach to sustainable crop production by reducing crop loss in various ways. This might result in the extensive use of PV devices in the near future. PV-based plant protection equipment/devices are primarily utilized in protecting crops from birds, weeds, or insects. The utilization of PV systems for different applications constitutes a new era in agriculture, horticulture, and forest sectors. A PV system is a potential alternative, offering more opportunities in operating different types of electricity-based agricultural equipment. The development of devices with simple construction/operation for plant protection may work well on small-scale farms.

Video Share
Video Share is an IP Multimedia System (IMS) enabled service for mobile networks that allows users engaged in a circuit switch voice call to add a unidirectional video streaming session over the packet network during the voice call. Any of the parties on the voice call can initiate a video streaming session. There can be multiple video streaming sessions during a voice call, and each of these streaming sessions can be initiated by any of the parties on the voice call. The video source can either be the camera on the phone or a pre-recorded video clip. Video share is initiated from within a voice call. After a voice call is established, either party (calling or called) can start a Video Share (VS) session. The sending User is then able to stream one-way live or recorded video. The default behavior is that the receiving handset will automatically go to speakerphone mode when video is received, unless the headset is in place. The sender will be able to see what is being streamed on their handset, along with the receiving User. In this scenario, the sender can “narrate” over the CS audio connection while both parties view the video. Both users will have the ability initiate a video share session, and either the sender or recipient in a video share session can terminate the session at any time. As part of the VS invitation, the recipient can choose to reject the streamed video. It is intended that both sender and receiver will receive feedback when the other party terminates a session or the link drops due to lack of coverage. The Video Share service is defined by the GSM Association (GSMA). It is often referred to as a Combinational Service, meaning that the service combines a circuit switch voice call with a packet switch multimedia session. This concept is described in the 3rd Generation Partnership Project (3GPP) specification documents 3GPP TS 22.279, 3GPP TS 23.279 and 3GPP TS 24.279. The Video Share service requires a 3GPP compliant IMS core system. GSM Association has split the Video Share service definition into 2 distinct phases. The first phase (also called Phase 1) involves sharing a simple peer-to-peer, one-way video stream in conjunction with, but not synchronized to a circuit switch voice call. The second phase (also called Phase 2) introduces the Video Share Application Server in the solution and supports more complex features and capabilities, such as point-to-multipoint video share calls, video streaming to a web portal, and integration of video share with instant messaging. In the industry, Video Share is also referred to by other names such as See What I See and Rich Voice Call. Video Share is supported only in UMTS and EDGE (with DTM) networks. It is not supported in a GPRS or a CDMA network. The Video Share Client will drop a VS session when the handset transitions from UMTS to GSM during the session. The CS voice call will remain connected. AT&T (formerly Cingular) is one of mobile operators who have deployed the Video Share service nationwide.
