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

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

Detecting and Estimating Magnetic Fluid Properties by a Needle- Type GMR Sensor

Magnetic fluid or magnetic liquid are colloidal solutions of ultra-fine magnetic materials. Ferromagnet-ic materials consist of magnetic or other compound containing iron, nickel or cobalt, by a particle size of 5 to 50 nanometers, generally in a superparamagnetic, ferromagnetic or diamagnetic state. Magnetic fluids have a unique combination of strength and ability to interact with the magnetic field. This paper proposes to estimate and detect magnetic fluid weight density (concentration as low as 1%) by giant magnetore-sistance (GMR) sensor. The high sensitivity of the sensor is around 11 μV/μT. We propose to use it for bio-applications to characterize magnetic microfluides. For this application a Helmholtz coil was simulated and fabricated to make more uniform magnetic flux density.
