The Military

In the 4.0 era, which is progressing towards the 5.0 era, many studies have been carried out on visual sensing in robots. Which has a function as monitoring the movement of robots, especially in the scope of defense in the military. Technological developments in military defense equipment play an important role in supporting the defense of the country's territory. One of them is the development of sensing systems on robots, there are many methods to decide the view of enemy targets against weapons. One of them using the triangulation distance measurement method with the help of a stereo vision camera. This method has advantages in the combat robot system, which is that it can reduce people casualties caused by direct weapon contact with the enemy on the battlefield, especially in urban areas, while the principle of this study is to adopt the similarity of the human eye work system, this method requires a least of two images to get information coordinates the target distance to the camera. Then, we can process the distance information to decide the position of the target against the weapon, while the distance function is carried out to place the robot to take measures. From this background, the author wants to build a visual sensing system using stereo vision. Two webcams with 1080HD resolution each are placed parallel to the combat robot. From the images captured by the two cameras, it can observe the comparison gap between the position of the object with the term disparity, while the results of the disparity are usually used to calculate the distance of the real object and each camera has a viewpoint that can be known, so the distance of the object can be calculated by the more method of triangulation. The results show that the error between the real and the detected distance is 5% and that the camera resolution influences reducing the error.

Collection Methods

Conventional data collection methods that use Wireless Sensor Networks (WSNs) suffer from disadvantages such as deployment location limitation, geographical distance, as well as high construction and deployment costs of WSNs. Recently, various efforts have been promoting mobile crowd-sensing (such as a community with people using mobile devices) as a way to collect data based on existing resources. A Mobile Crowd-Sensing System can be considered as a Cyber-Physical System (CPS), because it allows people with mobile devices to collect and supply data to CPSs’ centers. In practical mobile crowd-sensing applications, due to limited budgets for the different expenditure categories in the system, it is necessary to minimize the collection of redundant information to save more resources for the investor. We study the problem of selecting participants in Mobile Crowd-Sensing Systems without redundant information such that the number of users is minimized and the number of records (events) reported by users is maximized, also known as the Participant-Report-Incident Redundant Avoidance (PRIRA) problem. We propose a new approximation algorithm, called the Maximum-Participant-Report Algorithm (MPRA) to solve the PRIRA problem. Through rigorous theoretical analysis and experimentation, we demonstrate that our proposed method performs well within reasonable bounds of computational complexity.

Yield Map

For gathering the final results of a season-round crop work, the georeferenced yield is a key piece of information. Harvesting equipment can be equipped with sensors to gather such information. Systems based on different technologies (impact, volume, optics, density, gravity…) will be explained for recording the yield flow inside the machinery, during the harvesting. Adaptations of yield sensors depending on the commodity, along with new sensing systems will be discussed. Sensor for quality quantification will also be explained, as they are important for certain crops. Basic procedures for the calibration of the sensing system and the proper registration of yield data to generate a successful yield map are presented.

Traditional games which involved fine motor skill are becoming obsolete nowadays, one of them is engklek. In addition to technological developments, the increasingly diminishing playgrounds and the growing individuality of the urban community has made traditional games much more forgotten. The preservation of engklek needs to be done through a contemporary approach involving recent technologies, one of them is using video games. Video games has potential to grow children's curiosity towards some knowledge that become increasingly rare. The aim of digitization of englek is to introduce traditional games in order to preserve the culture of traditional game for Indonesian children, especially for those whom live in urban areas today. The final result of this design process is an Android game application called PERON Engklek that would introduce traditional games through digital technology for children nowadays. By doing so, it would motivate them to play with their friends.

The Military

During the Civil War, Soviet workers had to fight against desertion and banditry. Since the majority of the country’s population was the peasantry, a confrontation arose with the Soviet government of that part of it that could not accept it. More often than not, peasants fell under such Bolshevik propaganda labels as “white gangs” or “gangs of deserters”, which had spread through the efforts of the party-Soviet propaganda machine. According to archival documents, local Soviet workers used terror not only to suppress resistance, but also as a forced measure caused by the real military-political situation in the Perm Governorate. The fight for the establishment of the power of the Soviets was fought against banditry, not desertion, and was fierce. Consequently, the widespread thesis in the history of the Civil War in the Perm Governorate about mass desertion is nothing more than an assumption. The line of the Eastern Front passed next to the Osinsky District, so the most fierce fight unfolded here, which in turn had an impact on the military-political situation in the governorate as a whole.

Developments in electronic communications are drastically changing what it means to be human and to interact with humans. The value of recent technological developments to artists is more than doing more, faster and better; it is also the ability to highlight and elevate humanness in new ways through art, even by appearing to replace the real with the virtual. New tools don’t simply replace humans, they allow human creators to shift into new realms of creation: creating dynamic systems and worlds instead of static products. This chapter will give consideration to the different types of presence manifest in various communications formats, stage presence in technology-mediated performance, and several artworks that bring new light to the artist’s approach to virtual worlds as a kind of counterpoint with reality.

American Geography

In the benchmark publication American Geography: Inventory and Prospect (1954), Joseph Russell reported that military geography had long been recognized as a legitimate subfield in American geography. Despite the occasional controversy surrounding the subfield since his assessment (Association of American Geographers 1972; Lacoste 1973), and the general period of drought it experienced within American academic geography during the Vietnam era, military geography displays unquestionable resilience at the dawn of the twenty-first century. The subfield links geography and military science, and in one respect is a type of applied geography, employing the knowledge, methods, techniques, and concepts of the discipline to military affairs, places, and regions. In another sense, military geography can be approached from an historical perspective (Davies 1946; Meigs 1961; Winters 1998), with emphasis on the impact of physical or human geographic conditions on the outcomes of decisive battles, campaigns, or wars. In either case, military geography continues to keep pace with technological developments and seeks to apply geographic information, principles, and tools to military situations or problems during peacetime or war. Throughout the twentieth century, professional and academic geographers made enormous contributions to the US Military’s understanding of distant places and cultures. The vast collection of Area Handbooks found in most university libraries, serves as testament to the significant effort by geographers during wartime. Although some of the work remains hidden by security classification, a casual glance at Munn’s (1980) summary of the roles of geographers within the Department of Defense (DOD) enables one to appreciate the discipline’s far-reaching impact on military affairs. The value of military geography within a theater of war can hardly be disputed. The subfield has also been important during peacetime, however, providing an important forum for the continuing discourse among geographers, military planners, political officials, and government agencies, as each relies upon geographic tools and information to address a wide range of problems within the national security and defense arenas. Despite the subdiscipline’s well-established tenure, the Military Geography Specialty Group is in its infancy. The time-lag is attributable to the subfield’s tumultuous experience during the Vietnam era and the associated demise that ensued.
