Several concatenated and iterative decoding approaches are used to improve the power efficiency of continuous phase modulation (CPM). First a symbol interleaver is used for serially concatenated CPM (SCCPM). Convergence of iterative decoding for this scheme can be earlier (lower SNR: Signal-to-Noise-Ratio) compared to bit interleaved SCCPM. Then a ring convolutional code (CC) is used as the out...
We present the extension of the successful Constant Perturbation Method (CPM) for Schrödinger problems to the more general class of Sturm-Liouville eigenvalue problems. Whereas the orginal CPM can only be applied to Sturm-Liouville problems after a Liouville transformation, the more general CPM presented here solves the Sturm-Liouville problem directly. This enlarges the range of applicability ...
The Cellular Potts Model (CPM) is a cellular automaton (CA), developed by Glazier and Graner in 1992, to model the morphogenesis. In this model, the entities are the cells. It has already been improved in many ways; however, a key point in biological systems, not defined in CPM, is energetic exchange between entities. We integrate this energetic concept inside the CPM. We simulate a cell differ...
Limbah cangkang kepiting dan kulit udang memiliki kandungan kitin yang dinilai berpotensi menjadi Chitosan Polymer Medium (CPM) sebagai bahan pelapis masker untuk menyisihkan zat toksik pada asap rokok. Bahaya sudah diidentifikasi memerlukan beberapa langkah pengendalian ke titik aman. Cara dapat digunakan mengendalikan bahaya rokok adalah dengan menggunakan masker. Oleh karena itu, penelitian ...
A recent study has provided evidence that the use of contralateral prophylactic mastectomy (CPM) is increasing.[1] Over the 5-year period from 1998 to 2003, the CPM rate doubled. Prior studies have shown that the surgical procedures chosen by patients are most commonly influenced by physician and surgeon recommendation. This has been observed in the choice of CPM as well.[2] The data strongly s...
The autologous mixed lymphocyte reaction (auto-MLR) measures the ability of non-T cells to stimulate autologous T cells to proliferate in tissue culture. The auto-MLR was studied in 1 1 patients with autoimmune thrombocytopenic purpura (ATP). Seven patients had decreased auto-MLR. which averaged 4440 ± 3364 cpm (SEM) compared to 1 5.360 ± 6905 cpm for simultaneously studied controls. The averag...
(LPS) is rare malignant tumor of fat cells in deep soft tissue that affects adults between the ages of 40 and 60 [1]. This tumor is extremely aggressive with high morbidity and mortality. World Health organization classifies LPS into five subtypes: well-differentiated (WDLPS)/Atypical lipomatous tumors (ALT); dedifferentiated (DDLPS); myxoid (MLPS); pleomorphic (PLPS); and mixed type LPS [2]. M...
Orthogonal Frequency Division Multiplexing (OFDM) system with Continuous Phase Modulation (CPM) mappers is considered. Such a system is known to provide superior bit error rate performance by virtue of the memory introduced by the CPM mapper compared to OFDM systems with conventional memoryless mappers such as BPSK and QPSK. In this paper, the ability of CPM mappers in an OFDM system to reduce ...
High peak-to-average power ratio of the transmit signal is a major drawback of multicarrier transmission such as OFDM. This paper describes Orthogonal Frequency Division Multiplexing (OFDM) system with Continuous Phase Modulation (CPM) mappers is considered. Such a system is known to provide superior bit error rate performance by virtue of the memory introduced by the CPM mapper compared to OFD...
