IMAGE RETRIEVAL BASED ON COMPLEX DESCRIPTIVE QUERIES

The amount of visual data such as images and videos available over web has increased exponentially over the last few years. In order to efficiently organize and exploit these massive collections, a system, apart from being able to answer simple classification based questions such as whether a specific object is present (or absent) in an image, should also be capable of searching images and videos based on more complex descriptive questions. There is also a considerable amount of structure present in the visual world which, if effectively utilized, can help achieve this goal. To this end, we first present an approach for image ranking and retrieval based on queries consisting of multiple semantic attributes. We further show that there are significant correlations present between these attributes and accounting for them can lead to superior performance. Next, we extend this by proposing an image retrieval framework for descriptive queries composed of object categories, semantic attributes and spatial relationships. The proposed framework also includes a unique multi-view hashing technique, which enables query specification in three different modalities - image, sketch and text. We also demonstrate the effectiveness of leveraging contextual information to reduce the supervision requirements for learning object and scene recognition models. We present an active learning framework to simultaneously learn appearance and contextual models for scene understanding. Within this framework we introduce new kinds of labeling questions that are designed to collect appearance as well as contextual information and which mimic the way in which humans actively learn about their environment. Furthermore we explicitly model the contextual interactions between the regions within an image and select the question which leads to the maximum reduction in the combined entropy of all the regions in the image (image entropy)

Television Dramas Standard in Pakistan

Pakistan television drama acknowledge by their innovation in past. When our drama telecast during golden age of PTV, roads would become empty. Time slot of 8:00 pm to 9:00 pm was prime time in every family. Things vicissitudes suddenly after influx of private channels and production of television dramas has negotiated the quality which was seen in dramas during the PTV era. After arrival of private TV drama channels needless serials on air on our TV screens. Nowadays if we calculate the dramas we all would soon over count the drams. But such extravagance of anything is bad in drama industry it came at price of declining standards of TV drama. The paper reviews how to bring quality back in Pakistani Dramas and what are the key factors to gain such popularity that PTV dramas used to have. This research paper is prepared on the basis of information and data acquired through meetings and interviews with several well known personalities of drama industry.</p

Petrographical Characters of Some important host rocks in Vizianagarm Manganese Ores Belt (A.P.), INDIA.

Petrographical study of various rocks types has been carried out in the present study area with the discovery of a new rock type- Crystalline algal Limestone. An attempt has been made to describe the petrographical characters of the following rock types encountered in the present study area.1. Calc-granulite2. Garnet-sillimanite-feldspathic gneiss3. Garnetiferous gneiss4. Feldspathic quartzite5. Crystalline algal limestone6. Shale7. Hypersthene gneiss.8. Granitic gneiss.The older Khondalite Group mainly consists of calc-granulite, garnet sillimanite gneiss, feldspathic quartzite and garnetiferous gneiss. The occurrence of crystalline algal limestone and red and green shales have been reported for the first time. The younger Charnockite Group mainly consists of hypersthene gneiss (porphyrroblastic and non-porphyroblastic) and granitic gneisses. Granite and pegmatite occur as intrusive bodies in thisgroup of rocks. The Khondalites and Charnockites show a complex structural pattern resulting from repeated periods of deformation. The general strike of rocks is NW-SE with local swings at places. These rocks at places show relict banding.Stratigraphically these are included within a thick succession of Pre- Cambrian rocks belonging to the Khondalite and Charnockite Groups of Dharwar Supergroup, that form a part of Eastern Ghat Complex of India. The manganiferous rocks that have been encountered in the Vizianagarm Manganese Ore Belt (A.P.) India are known as Kodurites. At different places the rock types constituting the host rocks of manganese are essentially garnet sillimanite gneiss (Chipurupalle and Garbham), quartzite and garnetiferous quartzite (Garbham, Koduru, Perapi &amp; Avagudem) andcalc granulites and gneisses (Koduru).Keywords: Pertrography, Vizianagram, Manganeses Ores, Khondalite, Charnockite, Calc-granulite, Garnet Sillimanite Gneiss, Felspathic Quartzite, Crystalline Algal Limestone

Branding Strategies of Service Small and Medium-Sized Enterprise Owners

Most enterprises in the United Arab Emirates are small and medium-sized enterprises (SMEs); some owners of these enterprises lack the knowledge of branding strategies to succeed financially. The purpose of this multiple case study was to explore branding strategies used by owners of some successful service SMEs. Krake\u27s funnel model for the role of brand management in SMEs was the conceptual framework used in the study. Data were collected from semistructured interviews with a purposeful sample of 6 owners of medium-sized service enterprises who used branding strategies to improve the financial performance of their companies, and a review of company documents and company websites. Data analysis was conducted using the principles of the content analysis method, which included identifying codes and themes. Findings indicated owners of SMEs should be the personification of their brand, must do internal branding, should use the Internet and social media for marketing and branding, and should use innovative marketing strategies to promote their brand. The implications of this study for positive social change include the potential for owners of SMEs, who successfully implement branding strategies, to participate in the social causes started by the local governments for the welfare of people and communities

THE ANALYSIS OF VARIOUS TCP SUB-VERSIONS AND MECHANISM FOR CONGESTION AVOIDENCE

TCP, the most widely used protocol on Internet, has a major problem in that its congestion control does not allow flows to obtain full bandwidth on fast-long distance links. A Performance analysis of TCP-controlled long file transfers in a WLAN in infrastructure mode also with Comparison and Analysis of Congestion Window for HS-TCP, Full-TCP and TCP-Linux in Long Term Evolution System Model is available in the literature with one of the main assumptions being equal window size for all TCP connections. In this paper, we extend the analysis to TCP-controlled long file uploads and downloads with different TCP windows. Our approach is based on the semiMarkov process considered in [1] and [2], but with arbitrary window sizes. We present simulation results to show the accuracy of the analytical model.

Frustratingly Simple but Effective Zero-shot Detection and Segmentation: Analysis and a Strong Baseline

Methods for object detection and segmentation often require abundant instance-level annotations for training, which are time-consuming and expensive to collect. To address this, the task of zero-shot object detection (or segmentation) aims at learning effective methods for identifying and localizing object instances for the categories that have no supervision available. Constructing architectures for these tasks requires choosing from a myriad of design options, ranging from the form of the class encoding used to transfer information from seen to unseen categories, to the nature of the function being optimized for learning. In this work, we extensively study these design choices, and carefully construct a simple yet extremely effective zero-shot recognition method. Through extensive experiments on the MSCOCO dataset on object detection and segmentation, we highlight that our proposed method outperforms existing, considerably more complex, architectures. Our findings and method, which we propose as a competitive future baseline, point towards the need to revisit some of the recent design trends in zero-shot detection / segmentation.Comment: 17 Pages, 7 Figure

Exploration of the Continental Margins of India

In mid 1970’s the Institute prepared a plan for systematic regional geological and geophysical surveys of the continental margins of India. This involved over 75,000 km of underway (bathymetric, side scan sonar, magnetic, gravity and seismic) surveys on tracks about 20 km apart, and collection of about 1500 seabed samples at about 10 to 20 km spacing. It was anticipated that the entire programme would require 22 ship’s months. This programme received considerable impetus from sponsored surveys of other organizations, chiefly the oil industry, ports and harbours as well as industries disposing of their effluents in the marine environment. By now the entire western continental shelf and a large part of the continental slope have been covered by about 68,314 km bathymetric surveys, 12,720 km side scan sonar surveys, 46,222 km magnetic surveys, 27,200 km seismic surveys (including 5,489 km multichannel seismic), and 9,065 km gravity surveys. Approximately 1500 seabed samples have been collected. These surveys, besides providing basic information on the morphology, sediments, and geochemistry of the sediments of the .western continental margin of India, have also led to the estimation of resources of offshore ilmenite placers and low grade phosphorite deposits. The data collected are proposed to be depicted in a series of maps showing the morphology, sediments and geochemistry of sediments

The Late Eocene-Early Miocene unconformities of the NW Indian Intraplate basins and Himalayan foreland:a record of tectonics or mantle dynamics?

A well-developed Late Eocene to Miocene unconformity, termed the Base Miocene Unconformity (BMU), is found throughout the intraplate basins of north-western India, and has previously been ascribed to Himalayan tectonics. This hypothesis is investigated by first describing the nature and age of the BMU in the northwest Indian intraplate basins, and then reconstructing the location of the BMU relative to the Himalayan deformation front at the time it formed. We suggest that formation of the BMU in western India cannot be related to Himalayan tectonic processes associated with plate loading and flexure unless the Indian plate had an elastic thickness of >125 km, which is highly unlikely. Furthermore, the resumption of deposition post-unconformity rules out inversion due to compression associated with India-Asia convergence as a cause, as these compressive forces are still present. We note the coeval nature of the unconformity in the NW Indian plate intraplate basins and the Himalayan peripheral foreland basin. If the unconformities of the Himalayan peripheral foreland basin and the NW Indian intraplate basins formed by a common process, uplift due to circulation in the mantle is the only possible regional-scale mechanism. Such circulation could be the result of the intrinsically time-dependent high-Rayleigh number convection in the mantle, which has resulted in well-documented unconformities elsewhere, or be the result of subducting slab break-off beneath the Himalaya
