Modeling of the Schemes for Organizing a Session of Person–System Interactions in the Information System for Critical Use Which Operates in a Wireless Communication Environment

In this article, for the first time, a new mathematical model of the schemes for organizing a session of person–system interactions between the registration center server of the information system for critical use (ISCU) and the terminal of the person-user in a wireless communication environment are presented. In contrast to the existing literature, this article uses the mathematical apparatus of queuing systems to describe the schemes of organizing the stochastic process of a session of person–system interaction in discrete or continuous time, namely, models of the type Geo/Geo/1 with group arrival and ordinary service for the case of discrete representation of time and models of the type M/G/1 for the case of continuous time representation. The use of the mathematical apparatus of queuing systems in the studies made it possible to obtain analytical expressions for comparing formalized schemes for organizing the person–system interaction according to such functional characteristics as the average time of downloading a finite number of data blocks into the terminal of the target person-user (average time that the request spent the server of the information system).

Şiirin Tanıklık Gücü: 1989 Zorunlu Göçünün Bulgaristan Türk Şiire Yansıması

Bu makalede, Bulgaristan Türklerinin 1989’da yaşadığı zorunlu göçün, bu sancılı sürece maruz kalan Bulgaristan Türk şairlerinin eserlerinde ne şekilde ele alındığı incelenmiştir. Makalenin amacı, 1989 zorunlu göçünün şiirin diliyle yazılan kapsamlı bir tarihçesini oluşturarak, edebiyatın tanıklık gücünü sergilemektir. Çalışmada, şiirin “tanıklık gücü” terimi ile göç konulu şiirlerin okurun dikkatini sürekli şiir metninden gerçek olayın kendisine (zorunlu göçe) doğru yönlendirerek, bu eserlerin tarih yazımını onaylama/sorgulama gücü ifade edilir. Çalışma, Bulgaristan hükümetinin 1989’da zorunlu göçle noktaladığı etnik eritme politikasının kısa bir tanıtımından sonra, bu sürecin farklı aşamalarını ele alan şiirlerle örneklendirir. 1989 zorunlu göçünü ele alan şiirler, iki alt başlık altında incelenmiştir: 1. Ayrılık şiirleri; 2. Kavuşma şiirleri. Ayrılık şiirleri, Bulgaristan Türklerinin doğup büyüdükleri ülkelerinden kovulmalarını yoğun bir hüzün duygusu ile anlatırken, totaliter rejimin akıl almaz politikalarını da lanetleyen eserlerdir. İkinci bölüm, Anavatan Türkiye’ye ulaşmanın coşku dolu mutluluğunu milliyetçi bir söylemle aktaran örneklerin irdelenmesi ile başlayıp, göçün doğurduğu özlem ve bölünmüşlük (ne Türkiyeli ne Bulgaristanlı olma durumu) gibi duygularla yüklü şiirlerin incelenmesi ile devam eder. Bu döneme ait bazı şiirlerin yansıttığı derin milliyetçilik ruhunu açıklamak için, çalışmaya göç öncesinde yaşanan baskıları anlatan şiirler de dahil edilmiştir. ENGLISH ABSTRACTThe testimonial power of poetry: representation of the 1989 forced migration in the poetry of the Turks from BulgariaThe article focuses on the representation of the 1989 Forced Migration (of the Turks from Bulgaria to Turkey) in the works of Turkish poets from Bulgaria who have themselves been victims of this tragic event. Providing a comprehensive poetic chronicle of the migration, the article aims to illustrate the testimonial function of poetry, namely its power to complement and/or challenge historiography by constantly pushing the reader’s attention from the poetic text to the original event (the forced migration) itsef. After a brief discussion of the 1989 Forced Migration as part of the assimilation policy of the Bulgarian Government, the article examines poems which reconstruct different stages of the process. The poems are divided into two main groups. The first group (departure poems) consists of works which illustrate the migrants’ painful separation from their birthplaces, relatives and neighbors. Infused with deep grief, they provide a mighty indictment of the policy of the totaliterian regime. The second group (arrival poems) starts with a discussion of poems which reveal the migrants’ joyful unification with the rescuing image of the Motherland (Turkey) and goes on with the analysis of works which report the subsequent stages in the migrant’s life which are marked by a sense of nostalgia and liminality. To explain the mood of strong nationalism which governs the majority of the poems, this section includes also works which report the repressions the migrants had been subjected to prior to their flight to Turkey.

Mapping the cloud-to-ground lightning occurrence in Fiji

Using the Time Of Group Arrival (TOGA) of sferics two year (Jan2003-Dec2004) annual average of about 3,200 and 1,200 cloud-to-ground (CG) flashes were recorded in the two larger islands, Viti Levu and Vanua Levu, Fiji. A two year average CG flash density showed maxima of 0.80 and 0.35 flashes/km2 per year in two islands. The diurnal variation showed peak activity between 14:00 hrs- 16:00 hrs LT and the seasonal variation showed enhanced lightning incidences during November-April. Data from Lightning Imaging Sensor (LIS) aboard the NASA Tropical Rainfall Measuring Mission (TRMM) satellite are also presented for the same period at the two locations. Lightning in a 10 km �10 km area was compared with total rain accumulation at a site midway in the area which shows good correlation.
