Design and analysis of a novel low PDP full adder cell

This paper, presents a new full-swing low power high performance full adder circuit in CMOS technology. It benefits from a full swing XOR-XNOR module with no feedback transistors, which decreases delay and power consumption. In addition, high driving capability of COUT module and low PDP design of SUM module contribute to more PDP reduction in cascaded mode. In order to have accurate analysis, the new circuit along with several well-known full adders from literature have been modeled and compared with CADENCE. Comparison consists of power consumption, performance, PDP, and area. Results show that there are improvements in both power consumption and performance. This design trades area with low PDP

FARS: Fuzzy Ant based Recommender System for Web Users

Recommender systems are useful tools which provide an adaptive web environment for web users. Nowadays, having a user friendly website is a big challenge in e-commerce technology. In this paper, applying the benefits of both collaborative and content based filtering techniques is proposed by presenting a fuzzy recommender system based on collaborative behavior of ants (FARS). FARS works in two phases: modeling and recommendation. First, user’s behaviors are modeled offline and the results are used in second phase for online recommendation. Fuzzy techniques provide the possibility of capturing uncertainty among user interests and ant based algorithms provides us with optimal solutions. The performance of FARS is evaluated using log files of “Information and Communication Technology Center” of Isfahan municipality in Iran and compared with ant based recommender system (ARS). The results shown are promising and proved that integrating fuzzy Ant approach provides us with more functional and robust recommendations

The analysis results obtained that the passengers of the dominant airport in the selection of modes of cost attributes than on other attributes. From the result of regression analysis, the influence of independent variable to the highest dependent variable is when the five attributes are used together with the R square value of 8.8%. The relationship between cost, time, headway, time acces and service with the selection of modes, the provision that states whether or not there is a decision. The significance of α = 0.05 with chi-square. And the result of Crame\u27s V test average of 0.298 is around the middle, then the relationship is moderate enough

Characteristics of alpha projectile fragments emission in interaction of nuclei with emulsion

The properties of the relativistic alpha fragments produced in interactions of 84^Kr at around 1 A GeV in nuclear emulsion are investigated. The experimental results are compared with the similar results obtained from various projectiles with emulsion interactions at different energies. The total, partial nuclear cross-sections and production rates of alpha fragmentation channels in relativistic nucleus-nucleus collisions and their dependence on the mass number and initial energy of the incident projectile nucleus are investigated. The yields of multiple alpha fragments emitted from the interactions of projectile nuclei with the nuclei of light, medium and heavy target groups of emulsion-detector are discussed and they indicate that the projectile-breakup mechanism seems to be free from the target mass number. It is found that the multiplicity distributions of alpha fragments are well described by the Koba-Nielsen-Olesen (KNO) scaling presentation. The mean multiplicities of the freshly produced newly created charged secondary particles, normally known as shower and secondary particles associated with target in the events where the emission of alpha fragments were accompanied by heavy projectile fragments having Z value larger than 4 seem to be constant as the alpha fragments multiplicity increases, and exhibit a behavior independent of the alpha fragments multiplicity.Comment: 33 pages, 8 figures and 3 tables (in press

Pengoptimalan Pembangunan Flyover Pramuka Melalui Pengaturan Intensitas Bangunan di Kota Bandar Lampung

Kota Bandar Lampung sebagai ibukota Provinsi Lampung menyebabkan jumlah pergerakannya tinggi sehingga kemacetan lalu lintas tidak dapat dihindari pada beberapa ruas jalan di Kota Bandar Lampung. Penyelesaiaan atas permasalahan tersebut oleh pemerintah Kota Bandar Lampung dilakukannya pembangunan flyover di beberapa ruas jalan yang mengalami kemacetan, salah satunya di ruas Jalan Pramuka. Flyover Pramuka dibangun pada tahun 2017 dan memiliki daya tahan menjaga arus stabil berjangka waktu hingga 10 tahun dari saat keberadaan flyover memberikan pengaruh positif terhadap penurunan volume capacity rasio (VCR). Waktu jenuh jalan eksisting dan flyover diketahui dengan menggunakan metode analisis sensitivitas melalui pembebanan bertahap. Hasil penelitian menunjukkan bahwa pembangunan flyover menyebabkan kondisi jalan eksisting dan sisi flyover mengalami waktu jenuh pada tahun 2028-2038 sehingga penting untuk Pemerintah Kota Bandar Lampung mengantisipasinya dengan menetapkan aturan intensitas bangunan. Jenis kegiatan yang terdapat di wilayah internal dan wilayah eksternal di dominasi oleh perdagangan dan jasa. Pengaturan intensitas bangunan sebagai bentuk pengoptimalan pembangunan flyover penting untuk memperhatikan pula arahan rencana struktur ruang yang ikut mempengaruhi beban lalu-lintas pada jalan eksisting dan flyover. Kata Kunci: flyover, intensitas bangunan, wilayah internal, wilayah eksterna

Pengaruh Pintu Keluar Mall Bumi Kedaton Dan U Turn Sebelum Lintas Jalan Rel Di Jalan Sulta Agung (Studi Kasus Simpang Jl. Teuku Umar – Jl. ZA. Pagar Alam – Jl. Sultan Agung)

This research used primary data and secondary data. The primary data is obtained from the directsurvey result in the form of geometry data, environmental condition data, traffic flow, signaltiming, and long queues. Secondary data consists of the population in Bandar Lampungat 2012that is get from BPS Lampung Province. Data analysis is used the Indonesian Manual HighwayCapacity in 1997 for Signalized Intersections. Based on calculations, it can found that theintersection level of service at aftrenoon peak hour was F with a delay amount 61,50sec/pcu, levelof service at evening peak hour was F with a delay amount 88, 20sec/pcu, and level of service atnight peak hour was F with a delay amount 60, 29sec/pcu. Similarly, with the U Turn result canobtained the intersection level of service at afternoon peak hour was B, level of service at eveningpeak hour was B, and level of service at night peak hour was A.It indicates that the performance ofintersectionis not optimal. To increase the performance of the intersection, need make a changesin the pattern of setting time control become the pattern of not setting time control based on thepeak condition by changing the cycle time, green time, and inter green time. And therecommendation needed for the handling of openings U Turn on Jl. Sultan Agung

The quantum theory of the electromagnetic field

The present work is concerned with de Broglie's quantum theory of light. It is assumed that the photon is described by a Hermitian wave function with 16 components. Using this wave function it is shown that the 32 of de Broglie's equations are reduced to one set of 16 equations in the form: [equation] where the [alpha]'[rho] are Dirac matrices and [psi] is a matrix with 16 components. The electromagnetic quantities associated with the photon are described by means of the Dirac matrices operating on [psi] in a specified way. It is shown also that these electromagnetic quantities satisfy Maxwell's equations as a result of the equation the interaction between an electron and a photon is developed and the matrix elements for the radiation transitions are calculated. It is further shown that the above wave equation can be considered as the superposition of two similar wave equations, one for the positive energy photons and the other for the negative energy photons. To each of these states there corresponds electromagnetic quantities defined by the above method. It is the superposition of these fields which gives rise to the reality of the electromagnetic field, found in experience. The wave mechanics of the positive energy photon is discussed and the method of second quantization is applied to its wave function, from which we deduce the commutation relations for the complex fields. <p
