Aerial Combat

The fighting in the air-to-air combat and air-to-surface combat represents a relatively new type of combat, happening for a period of only around seventy years. In these years a quick technological advancement took place and caused the development of very primitive weapons to the present beyond the visual range or point-to-shoot capabilities of nowadays aircraft. Though aerial combat fundamentals remained very similar to those in the past, seasoned only by actual combat and exercises for training purposes. Although these standards remained almost untouched, the technological advancement in aircraft design and weapon systems is immense. This applies also to the fighter jet aircraft called F-16. The F-16 is one of the most widespread fighter jets ever produced, if not the most. It is important to improve the aircraft design and its systems for navigation, orientation, and maybe most importantly, its ‘weaponry and surrounding accessories.

Computer generated forces (CGFs) play blue or red units in military simulations for personnel training and weapon systems evaluation. Traditionally, CGFs are controlled through rule-based scripts, despite the doctrine-driven behavior of CGFs being rigid and predictable. Furthermore, CGFs are often tricked by trainees or fail to adapt to new situations (e.g., changes in battle field or update in weapon systems), and, in most cases, the subject matter experts (SMEs) review and redesign a large amount of CGF scripts for new scenarios or training tasks, which is both challenging and time-consuming. In an effort to overcome these limitations and move toward more true-to-life scenarios, a study using grammatical evolution (GE) to generate adaptive CGFs for air combat simulations has been conducted. Expert knowledge is encoded with modular behavior trees (BTs) for compatibility with the operators in genetic algorithm (GA). GE maps CGFs, represented with BTs to binary strings, and uses GA to evolve CGFs with performance feedback from the simulation. Beyond-visual-range air combat experiments between adaptive CGFs and nonadaptive baseline CGFs have been conducted to observe and study this evolutionary process. The experimental results show that the GE is an efficient framework to generate CGFs in BTs formalism and evolve CGFs via GA.

New Type

Reflection on the history of the novel usually begins with consideration of the social, political, and economic transformations within society that favored the “rise” of a new type of narrative. This remains true even with the numerous and important studies appearing during the past ten years, which relate the novel to an everbroadening spectrum of ideological issues—gender, class, race, and, most recently, nationalism. Yet a history of the genre might reflect not just on the novel’s national, but also its transnational, trajectory, its spread across the globe, away from its original points of emergence. Such a history would take into account the expansion of western markets—the growing exportation of goods and ideas, as well as of social, political, and cultural forms from the West—that promoted the novel’s importation by nonwestern societies. Furthermore, it could lead one to examine the very interesting inverse relationship between two kinds of migration, both of which are tied to the First World’s uneven “development” of the Third. In a world system that draws out natural resources in exchange for technologically mediated goods, the emigration of laborers and intellectuals from peripheral societies to the centers of power of the West and the immigration of a western literary genre into these same societies must be viewed as related phenomena.

The article is devoted to the consideration of the worldview positions of famous educators of the past century regarding the state of school education among Muslims of the North Caucasus region. It is proved that the enlighteners advocated the creation of a new type of national non-class school and the construction of the didactic foundations of the educational process in it. The novelty of the work is that, based on the analysis of the views of the advanced intelligentsia of the region, aimed at understanding the current socio-cultural situation, an attempt was made to scientifically understand the problems and prospects for the development of the Muslim educational system of the past from the point of view of the modern scientific paradigm. The practical significance of the publication lies in expanding the understanding of the system of Mohammedan education in the context of its historical heritage, which will help to comprehend modern problems associated with the reform of general and vocational education in the national Muslim republics.

Historic Cities

Nowadays, in the age of massive spatial transformations in the built environment, cities witness a new type of development, different in size, scale and momentum that has been thriving since late 20th century. Diverse transformation of historic cities under modernisation has led to concerns in terms of the space and time continuity disintegration and the preservation of historic cities. In a similar approach, we can state that city and city space do not only consist of present, they also consist of the past; they include the transformations, relations, values, struggles and tensions of the past. As it could be defined, space is the history itself. Currently, we would like to display how Chernivtsi cultural and architectural heritage is perceived and maintained in the course of its evolution. Noteworthy, Chernivtsi city is speculated a condensed human existence and vibes, with public urban space and its ascriptions are its historical archives and sacred memory. Throughout the history, CHERNIVTSI’s urban landscape has changed, while preserving its unique and distinctive spirit of diversity, multifacetedness and tolerance. The city squares of the Austrian, Romanian and Soviet epochs were crammed with statuary of royal elites and air of aristocracy, soviet leaders and a shade of patriotic obsession, symbolic animals and sacred piety – that eventually shaped its unique “Bukovynian supranational identity”. Keywords: Chernivtsi, cultural memory, memory studies, monuments, squares, identity.

Psychosexual Dysfunction

Many writers have shown their preoccupation with and interest in the representation of the fantastic body over the past centuries. The figure of the vampire, werewolves, and zombies keep coming back in those works although today’s monsters are humanized. In Contemporary Young Adult fantasy, readers are presented with characters that usually adapt to the real world. The fantastic body does no more refer to psychosexual dysfunction but generates mainly from socioeconomic and cultural malaise (Badley, 17-18). In other words, the fantastic becomes a virtual reality that symbolizes the changing ‘self’ within the postmodern era though contemporary literature has transcended the actual environment as it copes with technological advancement. Unlike other fantasy fiction, Meyer has focused on traditional fantastic creatures originating in folklores and myths; they are an integral part of the fantastic as they cross lines between natural and supernatural elements. The present paper aims at addressing the representation of body transformations into vampires and werewolves in Stephenie Meyer’s The Twilight Saga. It will evaluate body metamorphosis into vampires and werewolves discovering new dimensions of one’s own identity and personality. It will further demonstrate how Meyer has succeeded in creating her own monsters without untying some of the mythical substratum.

New Evidence

This paper presents a retrospective investigation into the performance of a new type of flexible-arch configurations in Shimenzi arch dam based on the past ten-year-long field measurements. The flexible-arch configurations are mainly comprised of artificial short joints at the middle downstream surface and a middle contraction joint with hinged well and enlarged arch ends with bending joints. Fundamental design considerations of these components are provided, and their contributions to the performance of Shimenzi arch dam are discussed in detail using the monitoring data from joint meters, strain gauges, and thermometers. Some elementary numerical studies have been conducted on a typical arch structure with different arrangements of artificial joints. Both the field data and numerical results prove well the effectiveness of the purposely built short joints and the middle contraction joint on the relaxation of tensile stress mobilization. Field survey data also clearly demonstrate the significance of the hinged well at the upstream side of the middle joint for a continuous arch force transfer.

Anatomical Area

Objective Over the past few years bipolar electrocoagulation techniques in neurosurgery have been continually improving. However, limited access during endoscopic endonasal transsphenoidal surgery (EETS) for central skull base pathologies and the requirement of very precise coagulation in that dedicated anatomical area requires further refinement of bipolar coagulation instruments. We describe our experience (effectiveness of coagulation, intraoperative handling, and the use as a dissecting tool) with a new type of coagulation forceps, the Calvian endo-pen (Sutter Medizintechnik, Freiburg, Germany) during EETS. Method From June to August 2015, 12 patients with central skull base lesions (9 with a pituitary adenoma and 1 each with epidermoid, hemangioma, and juvenile angiofibroma) were operated on with the Calvian endo-pen. Results The application of the Calvian endo-pen was feasible in all cases. The angled thin tips proved to be very effective and precise for soft tissue coagulation to achieve hemostasis. Even very small vessels could be occluded selectively. It was also helpful for outward dissection in separating normal from tumor tissue. Conclusion The use of the Calvian endo-pen is safe and effective during EETS for central skull base pathologies. Its ease in intraoperative handling (maneuverability, cleaning) and precise coagulation makes it a promising instrument for EETS.

“The greatest legacy one can pass on to one’s children and grandchildren is not money or other material things accumulated in one’s life, but rather a legacy of character and faith”. Evangelist Billy Graham.Dining together each night my father- in -law converses with us on how he was born and brought up by his parents long back. having his mother alive all hail and hearty, an old lady of 100 makes him recall his childhood each time he sees her. he flips back on how his father gave him valuable advices on lessons of life, and continues to walks on the principals that his father has imbibed on him as a young boy and he carries a strong impression of his fathers teachings, he expects that the coming generation should live a life as they then lived. childhood in itself is a sweet memory for each one of us, we all have our own bunch of memories to share. childhood is even the most correct time to mould a raw person into a fine personality. living in the 21st century world, things have seemed to be changing a lot. parenting, raising children has become a far more different aspect. since parenting is also an ethical and moral issue, perspective may vary according to the culture and civilization for different people belonging to different set ups. as health personals we too come across many cases that arise merely due to maladjustments or psychological impairments that many a times lead to serious psychiatric problems. the third important thing is that parenting as a complete process and according to the changing time parenting is not the same as it used to be in the past. in the previous years we have been undergoing tremendous technological advancement which in terms is a boon for us. our lifestyles have heavily changed, we no more live in an joined family, we all are working parents and our outlook for a settled life has changed the world around us. we all live in the a world that is modernly civilized. leaving our civilization far behind. raising kids in this advanced world is a challenge indeed. since technology has brought curses as well as boons to our lives. we need to balance them both. things may be difficult but not impossible.

The development of new technologies has had an impact on human behavior and communication from time immemorial. With the growing rate of technological advancement during the past 100 years, the changes have occurred even more rapidly. In an effort to understand the effects of one medium on human behavior and communication, this article explores and synthesizes research that has been conducted over the past 30 years, in what has come to be known as the chatroom. The chatroom, in the form of Internet Relay Chat (IRC), was developed in the late 1980s, and has been growing in popularity ever since. Chatrooms are Web-based platforms that allow synchronous, written communication between two or more interested participants in a forum that is potentially open to other interested participants.
