Battle Damage Assessment (BDA) is to assess the damage degree of enemy’s target after being attacked. In modern war, combat commanders always make decision on the basis of BDA. In this paper, an automatic method for assessing the damage extent of an attacked airport based on the image taken before and after a strike is described. Firstly, the airport blockade condition is analyzed and damage assessment criteria of airport are proposed. Secondly, three steps of the image information pretreatment are carried out and a reliability analysis method of image information is proposed. Lastly, damage assessment result is calculated to verify the validity and availability of the proposed method.

Abstract: This research aims to analyze the impact of Janti Flyover Construction toward the growth of layout at Janti Urban Area, including structured space, open space, and linkage. Method used for data collecting are observation, air photograph monitoring, and interview, whereas the analysis method is qualitative description, which is the superimposed method of two layers, that are the layout condition before and after flyover construction. The result shows that the impact of Janti Flyover construction can be seen on building mass (solid), the increasing number of open spaces, including the road network, parking place, and park, whereas the relation between spaces, visually and structurally, can be seen on the growth of buildings which have new shapes and styles, therefore the performance of the overall building does not have a proportional shape. Considering Janti Street at the collective relation, its role is getting stronger as the main frame road network.Keywords: Flyover construction, layout changing, Janti AreaAbstrak: Penelitian ini bertujuan untuk menganalisis pengaruh pembangunan Jalan Layang Janti terhadap perkembangan tata ruang Kawasan Janti, meliputi ruang terbangun, ruang terbuka, serta hubungan antar ruang (“linkage”). Metode pengumpulan data dilakukan melalui observasi, pengamatan foto udara, dan wawancara; sedangkan metode analisis melalui deskripsi secara kualitatif yang berupa “superimposed method” dari dua lapisan kondisi lahan, yakni kondisi tata ruang sebelum dan sesudah pembangunan jalan layang. Hasil penelitian menunjukkan bahwa pengaruh pembangunan Jalan Layang Janti terdapat pada massa bangunan (“solid”), pertambahan ruang terbuka yang berupa jaringan jalan, parkir, dan taman; sedangkan pada hubungan antar ruang ̶ secara visual dan struktural ̶ yakni tumbuhnya bangunan dengan bentuk dan gaya baru, sehingga bentuk tampilan bangunan secara keseluruhan tidak proporsional. Pada hubungan kolektif, Jalan Janti semakin kuat perannya sebagai kerangka utama jaringan jalan.Kata kunci : Pembangunan jalan layang, tata ruang, Kawasan Janti

This research examines the agenda and frames used by the Reporter newspaper editorial coverage of issues and actors before and after the reform in Ethiopia. The study applies a quantitative content analysis method and examined 99 (Period 1 = 57 and Period 2 = 42) editorials in all periods. The source of data and the period of data collection were purposely selected. The results indicated that societal issues, government, and party issues were frequent in both periods. The professional journalist was the only Author in both periods. More government criticism and more reforms were mentioned before the reform. Compared with editorials published before and after the reform, noticeable changes were observed in government critique, attribution of responsibility frames, human interest frames and economic issue frames. However, content selection, sources of information, mentioned reforms, conflict relationship frames, and ideological frames didn’t have relationship with the date of publication. Finally, the Reporter editorials coverage did change significantly in many respects, although it is difficult to determine the causes of the changes—economic factors, reduced political control, social changes or globalization forces.

Anchor bolts are set in some elastomeric bearings of large-span column-supported spatial steel roofs. Besides helping the bearing in-site assembly, the bolts play the roles of sliding position limitation and vertical anchorage. To analyze the effect of bearings on nonlinear structural behavior, the bearing stiffness change is studied just before and after the elastomer pad is in contact with the bolts. For the bearing that the pad is glued with the top/bottom steel plates, three kinds of relation of pad and bolts are discussed and an approximate horizontal stiffness formula is obtained with parametric analysis method. Based on the analysis results a stiffness expression for sliding elastomeric bearings is deduced. To solve the computational problem caused by the bearing stiffness changes, an improved imbalance force vector formula is proposed. Case study shows that the bolts have influence upon the computed results more significantly.

The paper seeks to verify that to create favourable environment to enhance branding-based integrated business structures development, it is critical to ensure management effectiveness of consolidation processes and to increase the owners’ profits. To attain this objective, a range of methodological approaches, tools and methods for consolidation efficiency forecasting and evaluation have been suggested. The author's approach to managing consolidation processes refers to the systems theory and profit management. The bulk of the proposed solution is to examine the effects of consolidation processes on owners’ profits subject to the group operation as a system of brand development. As a principal tool to achieve this goal, the study proposes a pre-project analysis method which consists of separate procedures to assess the effects on: strategic location – through the developed graphical mathematical model; production and economic efficiency – through the assessment of changes in integrated structures of business (ISB) cash flows subject to synergistic effect calculated using a cognitive map; the risk exposure – through business simulation. The core of the analysis is modelling of financial and operation activities of the group of companies before and after the consolidation, based on the adjusted input-output model of consolidated financial statement specifics in industrial companies. The final procedure in pre-project consolidation analysis is to assess the consolidation projects by means of multi-criteria decision-making analysis method. The study also suggests a broader approach to the consolidation process – from a project portfolio perspective that maximizes the utility under budget constraints.

In this study, the microstructural evolution of a non-reactive porous model food (sponge cake) during freezing was investigated. Sponge cake samples were frozen at two different rates: slow freezing (0.3 °C min−1) and fast freezing (17.2 °C min−1). Synchrotron X-ray microtomography (µ-CT) and cryo-scanning electron microscopy (Cryo-SEM) were used to visualize and analyze the microstructure features. The samples were scanned before and after freezing using a specific thermostated cell (CellStat) combined with the synchrotron beamline. Cryo-SEM and 3D µ-CT image visualization allowed a qualitative analysis of the ice formation and location in the porous structure. An image analysis method based on grey level was used to segment the three phases of the frozen samples: air, ice and starch. Volume fractions of each phase, ice local thickness and shape characterization were determined and discussed according to the freezing rates.

It is found that the traditional BDA methods are not appropriate the system target BDA. A new method of the system target BDA is proposed in this paper. Firstly, based on Hierarchy Analysis Method (AHP), the system target function index system is set up. Secondly, the step of system target function damage assessment method is analyzed and proposed based on Fuzzy Analytic Hierarchy Process (FAHP). Finally, an example of air base damage assessment is given to verify the validity and availability of the proposed method.
