Electromagnetic emission-aware schedulers for the uplink of OFDM wireless communication systems

The popularity and convergence of wireless communications have resulted in continuous network upgrades in order to support the increasing demand for bandwidth. However, given that wireless communication systems operate on radiofrequency waves, the health effects of electromagnetic emission from these systems are increasingly becoming a concern due to the ubiquity of mobile communication devices. In order to address these concerns, we propose two schemes (offline and online) for minimizing the EM emission of users in the uplink of OFDM systems, while maintaining an acceptable quality of service. We formulate our offline EM reduction scheme as a convex optimization problem and solve it through water-filling. This is based on the assumption that the long-term channel state information of all the users is known. Given that, in practice, long-term channel state information of all the users cannot always be available, we propose our online EM emission reduction scheme, which is based on minimizing the instantaneous transmit energy per bit of each user. Simulation results show that both our proposed schemes significantly minimize the EM emission when compared to the benchmark classic greedy spectral efficiency based scheme and an energy efficiency based scheme. Furthermore, our offline scheme proves to be very robust against channel prediction errors

KAJIAN SEMIOTIKA KUMPULAN PUISI PENDIDIKAN JASMANI DAN KESUNYIAN KARYA BENI SATRYO (DALAM PERSPEKTIF A. TEEUW)

Objective literary analysis is to give meaning and aesthetic values based on the reality of literary texts. Semiotics approach literature as a sign, or as semiotics symptoms. The literary work got significant if it had embraced, interpreted, and evaluated by the reader. The reader’s intention is the literary main characteristic, only with it’s work literature reaches aesthetic realization and becomes an aesthetic object. Demolition by codes can help the literature analysis to describes the experience of significance and aesthetic value. Poetry collection Pendidikan Jasmani dan Kesunyian by Beni Satryo has complex structure and its own signature, with analysis of language code, literary code, and cultural code contained in the text can help impart meaning and aesthetic value. So that the convention and invention are known on the text. From here it can be defined the problem of this research: (1) form of a language coded in poetry collection Pendidikan Jasmani dan Kesunyian by Beni Satryo; (2) form of a literary coded in poetry collection Pendidikan Jasmani dan Kesunyian by Beni Satryo; and (3) form of a cultural coded in poetry collection Pendidikan Jasmani dan Kesunyian by Beni Satryo. This type of research is qualitative research using the semiotics approach in A. Teeuw perspective. Data resource in this research is poetry collection Pendidikan Jasmani dan Kesunyian by Beni Satryo. Data found, processed several steps: (1) data reduction; (2) data presentation; and (3) conclusion. Based the process has several forms of language code, literary code, and cultural code was then reviewed with the theory of literary semiotics. Based on result and discussions, it’s obtained conclusion that in dismantling language code are discovered Beni Satryo’s selected potries still following the Indonesian Language convention, as for invetion in the form of tampering with spelling of words with intent to create comical effect on words that are most loads serious value. On desmantling of literary code be found that Beni Satryo’s selected poetries in general still following poetry convention, as for invention that exist in the form metaphor choice with things that are close, paltry, such things that give an element surprise in enjoying aesthetic value of those poetries. On desmantling of cultural code be found the attempt to say something of everyday life it is also culture, even though in the everyday life it is taken for granted

Advantages of nonclassical pointer states in postselected weak measurements

We investigate, within the weak measurement theory, the advantages of non-classical pointer states over semi-classical ones for coherent, squeezed vacuum, and Schr\"{o}inger cat states. These states are utilized as pointer state for the system operator $\hat{A}$ with property $\hat{A}^{2}=\hat{I}$, where $\hat{I}$ represents the identity operator. We calculate the ratio between the signal-to-noise ratio (SNR) of non-postselected and postselected weak measurements. The latter is used to find the quantum Fisher information for the above pointer states. The average shifts for those pointer states with arbitrary interaction strength are investigated in detail. One key result is that we find the postselected weak measurement scheme for non-classical pointer states to be superior to semi-classical ones. This can improve the precision of measurement process.Comment: 8 pages, 5 figure

On Achieving Diversity in the Presence of Outliers in Participatory Camera Sensor Networks

This paper addresses the problem of collection and delivery of a representative subset of pictures, in participatory camera networks, to maximize coverage when a significant portion of the pictures may be redundant or irrelevant. Consider, for example, a rescue mission where volunteers and survivors of a large-scale disaster scout a wide area to capture pictures of damage in distressed neighborhoods, using handheld cameras, and report them to a rescue station. In this participatory camera network, a significant amount of pictures may be redundant (i.e., similar pictures may be reported by many) or irrelevant (i.e., may not document an event of interest). Given this pool of pictures, we aim to build a protocol to store and deliver a smaller subset of pictures, among all those taken, that minimizes redundancy and eliminates irrelevant objects and outliers. While previous work addressed removal of redundancy alone, doing so in the presence of outliers is tricky, because outliers, by their very nature, are different from other objects, causing redundancy minimizing algorithms to favor their inclusion, which is at odds with the goal of finding a representative subset. To eliminate both outliers and redundancy at the same time, two seemingly opposite objectives must be met together. The contribution of this paper lies in a new prioritization technique (and its in-network implementation) that minimizes redundancy among delivered pictures, while also reducing outliers.unpublishedis peer reviewe

Rancang Bangun Fermentor Yogurt dengan Sistem Kontrol Logika Fuzzy Menggunakan Mikrokontroler ATMega32

Yogurt is milk fermented product that becomes popular recently. In yogurt processing, fermenter is the main device. Lactobacillus sp. and Streptococcus sp. are two probiotic bacteria species that are common to be used in yogurt fermentation process. Both bacteria grow well in a specific range of temperature between 40-45 C, so temperature control in fermenter operational becomes one of the important things to ensure speed and quality of fermentation process. Fermentation process is a process with high degree of uncertainty and categorized as non-linear time invariant system. Thus, classical control system method is difficult to be implemented. To overcome this issue, intelligent control system can be implemented to yogurt's fermenter temperature control. One of intelligent control system method that can be implemented is fuzzy logic-based control system. In this study, fuzzy control system has been designed and implemented for fermenter temperature control. Control system algorithm is integrated in ATMega16 (for On-Off logic control) and ATMega32 (for Fuzzy Logic control) microcontrollers. Experimental results of fermenter control system shows that temperature profile of fermenter with fuzzy logic control system is more stable by settling time around an hour and 15 minutes and error average of -0.36 oC. Fermentation process for 16 hours with fuzzy logic controller produce yogurt with pH value of 3.66, total number of Lactobacillus sp. is 4.85 x 10 cfu/mL and Streptococcus sp. is 1.34 x 106 cfu/mL

Being a mobile international postgraduate research student with family in the United Kingdom: conflict, contestation, and contradictions

The internationalisation of higher education has influenced the dramatic rise in the mobility of students, academics and knowledge across borders. There has been growing research interest focusing on international students studying abroad. While the student experience is an area of education that is often researched, most research focuses on experiences of undergraduate students. Also in the context of international students, greater research emphasis has been placed on the academic experiences and support available for undergraduates. While such research is important, less attention has been paid to the non-academic experiences of International Post-Graduate Research Students with Families (IPGRSF). This article seeks to fill this gap by focusing on the social worlds of IPGRSF in the UK, examining students’ nuclear family contexts that are often marginalised in discourse. The article legitimises the IPGRSF subaltern world by focusing on how students negotiate its demands; how they negotiate their roles as research students with their other roles as spouses and parents, and the interrelationships among these roles; and how the university as an institution interacts with the students’ subaltern world. The findings show that language plays a significant role in shaping the process of mobility as well as influencing the students’ and their families’ integration and networking in the host country. Also, the findings suggest that students often had positive experiences at departmental level, but felt let down by the wider university support
