A discrete-time performance model for congestion control mechanism using queue thresholds with QOS constraints
No full textYesThis paper presents a new analytical framework for the congestion control of Internet traffic using a
queue threshold scheme. This framework includes two discrete-time analytical models for the performance
evaluation of a threshold based congestion control mechanism and compares performance measurements through
typical numerical results. To satisfy the low delay along with high throughput, model-I incorporates one
threshold to make the arrival process step reduce from arrival rate ¿1 directly to ¿2 once the number of packets in
the system has reached the threshold value L1. The source operates normally, otherwise. Model-II incorporates
two thresholds to make the arrival rate linearly reduce from ¿1 to ¿2 with system contents when the number of
packets in the system is between two thresholds L1 and L2. The source operates normally with arrival rate ¿1
before threshold L1, and with arrival rate ¿2 after the threshold L2. In both performance models, the mean packet
delay W, probability of packet loss PL and throughput S have been found as functions of the thresholds and
maximum drop probability. The performance comparison results for the two models have also been made
through typical numerical results. The results clearly demonstrate how different load settings can provide
different tradeoffs between throughput, loss probability and delay to suit different service requirements
Performance modelling of a multiple threshold RED mechanism for bursty and correlated Internet traffic with MMPP arrival process
No full textYesAccess to the large web content hosted all over the world by users of the Internet engage
many hosts, routers/switches and faster links. They challenge the internet backbone to operate at
its capacity to assure e±cient content access. This may result in congestion and raises concerns over
various Quality of Service (QoS) issues like high delays, high packet loss and low throughput of the
system for various Internet applications. Thus, there is a need to develop effective congestion control
mechanisms in order to meet various Quality of Service (QoS) related performance parameters. In this
paper, our emphasis is on the Active Queue Management (AQM) mechanisms, particularly Random
Early Detection (RED). We propose a threshold based novel analytical model based on standard RED
mechanism. Various numerical examples are presented for Internet traffic scenarios containing both the
burstiness and correlation properties of the network traffic

ROMANSA CINTA PRAMUGARI, SUATU TINJAUAN PSIKOLOGI KEPRIBADIAN DALAM NOVEL “CINTA DI ATAS AWAN” KARYA GLENN ALEXEI
Get PDFSidiq Wahyu Nugroho. 2018. "The Romance of Love Stewardess, A Psychological Review of Personality in Glenn Alexei's Love Di Atas Awan Novel". Undergraduate Thesis Indonesian Language and Literature Faculty of Cultural Sciences Diponegoro University Semarang. Advisor: Laura Andri R.M, S.S., M.A. and Fajrul Falah, S.Hum., M.Hum.
This research is a library research, sourced from the novel Cinta di Atas Awan with the problems of the main character who experienced deterioration due to the unrequited love and ended up failing due to the existence of a third party. The deterioration of love makes the main character aware and re-open the heart to others, and ends beautifully with the anchoring of that love to his hardest friend. The author uses a theoretical psychology theory foundation that aims to analyze the personality structure of the main character in the struggle for his true love. The author uses structural theory to obtain data that is intended in the form of intrinsic elements as builders of the story which includes themes, characters and characterizations, plot, background as forming elements of literary works in the novel Cinta di Atas Awan.
The purpose of this study was to reveal the links between structural elements and examine the main character using the psychology theory of personality. The method used is the study of data collection, data analysis studies, and study of the presentation of the results of the analysis. This research produces three elements of psychology, namely id (das es), Karina Id, that is, she cries because the batis is hurt. Karina's ego (das ich) is her desire to remain Jimmy's lover. Super ego (das uber ich) Karina is that she thinks that what she is doing is wrong, that is, expecting something in vain. Karina realized that Alvin had been faithful and loved her. Emotional classification also appears in the study, namely sadness and love and reveals the romance of love.

عہدِ حاضر میں تربیت و کردار سازی کے تقاضے اور فکرِ اقبال کی معنویت
No full textIn every era, the importance of training and character building of the members of the society has been there. In the present material age, its importance and need has become even greater because as the development is increasing day by day in every field of life, human society is getting morally degraded. We are fortunate that, as a nation, we have a great personality like the thinker of Pakistan, whose thoughts and ideas continue to guide us even today. The universality of Iqbal's thought is a light for us even now and in the future era. The thoughts of Iqbal are the thoughts of every age because their basis is the insightful thoughts contained in the Holy Qur'an. Iqbal has the training and character-building equipment of every member of the Muslim Ummah. There is no doubt that if we, as a nation, make Iqbal's thoughts and ideas a part of our character both theoretically and practically, then we can regain our Identity

Probing dark energy with large galaxy surveys: systematics quantification and mitigation
No full textDark energy is a leading theory to explain cosmic acceleration, and forthcoming astronomical surveys have been specifically designed to probe this mysterious energy component of our universe. This thesis addresses aspects of using large galaxy surveys to study dark energy, which requires an unprecedented understanding and mitigation of systematics -- a challenge that can be addressed on two fronts: quantification of the impacts of systematics, and new tools to mitigate them. Here, we specifically study the impacts of three key systematics: those induced by 1) the telescope observing strategy, 2) the Milky Way dust, and 3) uncertain photometric redshifts. Focusing on the Legacy Survey of Space and Time (LSST) carried out by the Vera C. Rubin Observatory, we quantify the impacts of LSST observing strategy on large-scale structure studies, which is a probe of dark energy. We demonstrate the effectiveness of large translational dithers -- telescope-pointing offsets -- in increasing LSST survey uniformity and reducing systematic uncertainties (Awan et al., 2016; LSST Science Collaboration et al., 2017) -- a result that has now been adopted for the baseline LSST observing strategy. We also study the impacts of Milky Way dust on dark energy science and demonstrate that ~25% of the default LSST survey area would not be useful for extragalactic static science given the Milky Way dust extinction, motivating the reconfiguration of the LSST survey footprint to avoid high-extinction regions of the sky (Lochner et al., 2018; Olsen et al., 2018). And finally, we present a new formalism that provides a novel way to correct for redshift contamination arising from photometric redshift estimation (Awan & Gawiser, 2020). Specifically, we first introduce a general formalism to correct for sample contamination for photometric galaxy samples when measuring two-point angular correlation functions, and then a new weighted estimator that assigns each galaxy a weight in each redshift bin based on its probability of being in that bin, thereby fully utilizing the probabilistic distance information available for photometric galaxies. While these techniques are motivated by preparations for LSST, they are applicable to other large galaxy surveys like Dark Energy Survey (DES), Dark Energy Spectroscopic Instrument (DESI), Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), Euclid, and Wide-Field Infrared Survey Telescope (WFIRST).Ph.D.Includes bibliographical reference

Horizonless Worlds: Navigating the Persistent Present of the Border Regime
Get PDFThrough discussing the persistent present of displacement the essay argues that a politics of time is being mobilised as a biopolitical means of control in migrant lives. This can be seen in the circularity of displacement, deportation and return, where waiting and disorientation become forms of control. The discussion emerges from field research and interviews I carried out in the villages of north Punjab, Pakistan, where many people are caught in this chronopolitics of migration. The migrant experience of borders is read alongside a critical interrogation of the computational technologies deployed in border management, including EuroDAC and iMap. They produce a form of imperial temporality for which the horizon acts as a constitutive trope of progress, while simultaneously producing a sense of a horizonless world through the networked logic and ubiquity of datafication. I end with a discussion of how it may be possible to find other orientations within these normative spatiotemporalities of a bordered world.Theory, Territories & Transition
Female Oppression and Marginalization in Ice Candy Man by Sidhwa and the Holy Woman by Shahraz
Get PDFHow women are marginalized during the partition and after the partition is the major theoretical concern of this research. The present research reveals how Sidhwa and Shahraz address the gender oppression in Ice Candy Man and The Holy Woman respectively. Different researchers also argues that both writers describe the subjection of women to rape, conversion, forced marriages and various sexual abuses during partition and in the days of peace. The social structure of our society regards women as the honor of family. In case of marginalization she suffers the sexual violence; she gets profaned, resulting in the honor killing of the family. Sidhwa and Shahraz represent this oppression, marginalization, and violence as the shameful event. Shahraz and Sidhwa’s writings shows how the gender oppression work through their bodies. The selected novels of both writers show how the women are oppressed, marginalized, controlled, and exploited by the men under the shade of cultural, social, and religious traditions. This research will expose both the violent and subtle ways in which patriarchy repress the female to control in Pakistani society. The main focus of this research is to show how the works of these two female writers are critically examined to understand their role in exploring the issues of women that they face in this patriarchal society through the literary medium.
