Fixed-order H 2 and H = optimal deconvolution "lter designs

For the simplicity of implementation and saving of operation time, the "xed-order optimal deconvolution "lter design is appealing for engineers in signal processing from practical design perspective. In this study, a design method based on genetic algorithms is proposed to simultaneously treat with H 2 and H = optimal signal reconstruction design problem with prescribed"lter order. Genetic algorithms are optimization and machine learning algorithms, initially inspired from the processes of natural selection and evolutionary genetics. They tend to "nd the global optimum solution without becoming trapped at local minima. Both IIR and FIR cases are discussed in this study. The convergence property of our design algorithm is also discussed by Markov chain method. Two design examples of H 2 and H = optimal deconvolution with "xed-order "lters are given to illustrate the design procedure and the performance of the proposed design methods, respectively.

Impact of Thermospheric Mass Density on the Orbit Prediction of LEO Satellites

Many thermospheric mass density (TMD) variations have been recognized in observations and physical simulations; however, their impact on the low‐Earth‐orbit satellites has not been fully evaluated. The present study investigates the quantitative impact of periodic spatiotemporal TMD variations modulated by the empirical DTM2013 model. Also considered are two small‐scale variations, that is, the equatorial mass anomaly and the midnight density maximum, which are reproduced by the Thermosphere‐Ionosphere‐Electrodynamics General Circulation Model. This investigation is performed through a 1‐day orbit prediction (OP) simulation for a 400‐km circular orbit. The results show that the impact of TMD variations during solar maximum is 1 order of magnitude larger than that during solar minimum. The dominant impact has been found in the along‐track direction. Semiannual and semidiurnal variations in TMD exert the most significant impact on OP among the intra‐annual and intradiurnal variations, respectively. The zero mean periodic variations in TMD may not significantly affect the predicted orbit but increase the orbital uncertainty if their periods are shorter than the time span of OP. Additionally, the equatorial mass anomaly creates a mean orbit difference of 50 m (5 m) with a standard deviation of 30 m (3 m) in 1‐day OP during high (low) solar activity. The midnight density maximum exhibits a stronger impact in the order of 150±30 and 15±6 m during solar maximum and solar minimum, respectively. This study makes clear that careful selection of TMD variations is of great importance to balance the trade‐off between efficiency and accuracy in OP problems.
The Hedonic Econometric Model and Sourcing Management of the Cadastral Value of Land

The authors identified and evaluated the key hedonic factors of cadastral value of land for individual housing construction. In order to identify the observed factors determining the value of land plots, linear, power and exponential specifications of the regression hedonic model of cadastral value based on data on 160 land plots in the city were constructed based on the source management. Zelenodolsk in 2019. Â The empirical estimates of the specifications presented in the article confirmed the hypothesis about the influence of the distance to the region capital of the Russian Federation, the distance to the railway, the distance to the nearest recreational zone, the distance to the nearest water body, the land area on its cadastral value. The greatest impact on the cadastral value of land plots is the distance to the capital of the Russian Federation and the land area. The influence of the coefficient of the length of the land plot on its cadastral value in all built specifications was not confirmed. The quality of the results was tested using Fisher test, student test, regression equation specification error test (RESET), testing of regression residues on heteroskedasticity and autocorrelation (White test, Breusch-Pagan test). Â Â The results of the empirical estimates confirmed the feasibility of the practical use of this approach to the assessment of the cadastral value of land.
PENERAPAN MODEL PEMBELAJARAN MAKE A MATCH TERHADAP KEMAMPUAN KOMUNIKASI MATEMATIS SISWA DENGAN MENGUNAKAN GEOBOARD PADA MATERI BANGUN DATAR DI KELAS VII SMP NEGERI 2 BIREUEN

PENDAHULUAN Pendidikan merupakan pembinaan pribadi secara utuh dan lebih menyangkut kepada citra dan nilai, pendidikan juga sangat penting dalam kehidupan sehari-hari. Brubacher (Suwarno, 2008:21) mengatakan bahwa:Pendidikan adalah proses pengembangan potensi, kemampuan, dan kapasitas manusia yang mudah dipengaruhi oleh kebiasaan, kemudian disempurnakan dengan kebiasaan-kebiasaan yang baik, didukung dengan alat (media) yang disusun sedemikian rupa, sehingga pendidikan dapat digunakan untuk menolong orang lain atau dirinya sendiri dalam mencapai tujuan-tujuan yang telah dittapkan. Matematika merupakan salah satu pelajaran yang wajib diajarkan disetiap jenjang pendidikan mulai dari sekolah dasar sampai perguruan tinggi. Ini merupakan salah satu bukti bahwa matematika sangat penting dipelajari disekolah maupun kehidupan sehari-hari. Namun kenyatannya, matematika dikenal dengan pelajaran yang sangat rumit dan susah dipelajari siswa, sehingga banyak siswa yang tidak senang dengan pelajaran matematika. Padahal pembelajaran matematika memiliki manfaat sebagai sarana untuk mengembangkan kemampuan komunikasi, sistematis, dan kreatif, serta bekerja sama yang diperlukan siswa dalam pembelajaran agar dapat memiliki kemampuan, dan memanfaatkan informasi yang diperolehnya. Faktor lain yang mempengaruhi siswa sulit dalam pembelajaran matematika adalah rendahnya kemampuan komunikasi matematis siswa.
Response Versus Scan-Angle Assessment of MODIS Reflective Solar Bands in Collection 6.1 Calibration

The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments onboard the Aqua and Terra satellites have been operated for nearly two decades, producing high-quality earth observation data sets suitable for a broad range of scientific studies regarding the earth’s land, ocean, and atmospheric processes. The high radiometric accuracy of MODIS reflective solar band (RSB) calibration has also served as benchmark measurements for on-orbit cross-calibration studies. As the two MODIS instruments have operated well beyond their design lifespan of six years, the measurements from the onboard calibrators alone become inadequate to characterize the sensor’s response at all scan angles, as evinced by long-term drifts observed at certain scan positions of the Aqua-MODIS 0.64- and 0.86- $\mu \text{m}$ bands in Collection 6 (C6) data set. The latest MODIS Level 1B C6.1 data set incorporates earth-view response trending from invariant desert sites as supplemental inputs to characterize the scan-angle calibration dependencies for all RSB. This article presents a deep convective cloud (DCC)-based calibration approach for an independent evaluation of the MODIS RSB response versus scan-angle (RVS) performance in C6.1. The long-term calibration stability and RVS differences in C6.1 have been significantly improved for Aqua-MODIS RSB. The observed RVS differences of more than 2% in Aqua-MODIS C6 bands 1 and 2 have been reduced to within 1% in C6.1. Some RSBs of Terra-MODIS have suffered temporal drifts up to ~2% and calibration shifts up to 3%, particularly around 2016 when the Terra satellite entered into safe mode. The DCC approach has been found very effective in tracking the on-orbit RVS changes over time.
Perbandingan Algoritme K-Means Dengan Algoritme Fuzzy C Means (FCM) Dalam Clustering Moda Transportasi Berbasis GPS

Transportasi sudah menjadi kebutuhan dasar bagi masyarakat modern saat ini. Namun seringkali kebutuhan akan transportasi ini tidak diikuti dengan informasi mengenai ketersediaan trasnportasi di suatu tempat. Pada kasus ini, data dari GPS dapat digunakan untuk mengelompokkan moda transportasi yang tersedia serta memberikan informasi mengenai jumlah tiap-tiap moda transportasi yang tersebar dalam suatu wilayah dan waktu tertentu. Algoritme yang digunakan untuk memngelompokkan moda transportasi pada penelitian ini adalah K-Means dan Fuzzy C Means (FCM). Dua algoritme ini kemudian dibandingkan mana yang lebih baik hasilnya. Pengelompokan moda transportasi pada algoritme K-Means diperoleh dari jarak terkecil data moda trasnportasi dengan pusat klaster. Sedangkan pada algoritme FCM pengelompokan diperoleh dari nilai derajat keanggotaan terbesar. Setelah dilakukan pengujian sebanyak 10 kali, didapatkan rata-rata akurasi K-Means sebesar 58.46154 dan 70.86538 untuk algoritme FCM. Sedangkan untuk nilai silhouette Coefficient diperoleh rata-rata 0.4582670 untuk K-Means dan 0.440682 untuk algoritma FCM. Dari hasil pengujian, disimpulkan bahwa algoritme FCM lebih unggul dibandingkan K-Means.
Probing the Effects of Strong Electromagnetic Fields with Charge-Dependent Directed Flow in Pb-Pb Collisions at the LHC A Large Ion Expt Collabor

The first measurement at the LHC of charge-dependent directed flow ( v 1 ) relative to the spectator plane is presented for Pb-Pb collisions at ﬃﬃﬃﬃﬃﬃﬃﬃ s NN p ¼ 5 . 02 TeV. Results are reported for charged hadrons and D 0 mesons for the transverse momentum intervals p T > 0 . 2 GeV =c and 3 < p T < 6 GeV =c in the 5% – 40% and 10% – 40% centrality classes, respectively. The difference between the positively and negatively charged hadron v 1 has a positive slope as a function of pseudorapidity η , d Δ v 1 = d η ¼ ½ 1 . 68 (cid:2) 0 . 49 ð stat Þ (cid:2) 0 . 41 ð syst Þ(cid:3) × 10 − 4 . The same measurement for D 0 and ¯ D 0 mesons yields a positive value d Δ v 1 = d η ¼ ½ 4 . 9 (cid:2) 1 . 7 ð stat Þ (cid:2) 0 . 6 ð syst Þ(cid:3) × 10 − 1 , which is about 3 orders of magnitude larger than the one of the charged hadrons. These measurements can provide new insights into the effects of the strong electromagnetic field and the initial tilt of matter created in noncentral heavy ion collisions on the dynamics of light (u, d, and s) and heavy (c) quarks. The large difference between the observed Δ v 1 of charged hadrons and D 0 mesons may reflect different sensitivity of the charm and light quarks to the early time dynamics of a heavy ion collision. These observations challenge some recent theoretical calculations, which predicted a negative and an order of magnitude smaller value of d Δ v 1 = d η for both light flavor and charmed hadrons.
Biomechanics of Femoral Neck Fracture Fixation: A Review

Femoral neck fractures are a potentially devastating injury, and their successful treatment is complicated by the mechanical forces and limited blood supply intrinsic to the proximal femur. Attainment of an anatomic reduction of the fracture and stable fixation are essential for achieving union and minimizing complications. Many different implants are available, but cannulated screw fixation is supported by good biomechanical data and successful outcomes. There is some debate about the number of implants required and their configuration. Variants of the transcervical femoral neck fracture require particular attention. Vertically oriented and basicervical femoral neck fractures should be addressed carefully and treated according to the fracture's presentation to achieve rigid stability. Osteoporotic patients present a different challenge, as rigid fixation may be difficult to obtain.
Current Preclinical Models of Ovarian Cancer

Despite improvements in surgical and chemotherapeutic intervention of ovarian cancer over the recent decades, ovarian cancer remains the most lethal cancer in women. Notably, after an initial effective response to chemotherapeutic regimen, therapeutic resistance rises up leading to patient’s death. This scenario highlights the urgent need to develop novel diagnostic and therapeutic strategies. Recently, several efforts to better understand the molecular bases of ovarian cancer using integrated multiplatform molecular profiling have revealed an intrinsic complexity and heterogeneity among ovarian cancers. Concurrently, a growing body of evidences implies fallopian tube epithelium as the likely site of origin of the majority of ovarian cancers. This fallopian tube hypothesis has shifted the attention of ovarian cancer research from the ovarian surface epithelium to the fallopian tube epithelium leading to adjustment of in vitro and in vivo ovarian cancer models. In this review article, we critically summarize recent advances in ovarian cancer preclinical models that have the potential to accelerate and facilitate the discovery of more effective biomarkers and target drugs for personalized cancer therapy.

Transformations and Enhancement Approaches for the Large Deformation EAS Method

The computer simulation of large deformation solid mechanics requires highly efficient finite elements. One widely used method enabling the construction of such elements is the enhanced assumed strain (EAS) method (cf. [1]). Within that framework, many transformations for the enhanced as well as the compatible deformation gradient have been used in previous publications (see e.g. [2]). We propose a new frame‐invariant alternative which fulfills the patch test and exhibits superior bending performance. Finally, novel mixed finite element methods based on the combination of mixed finite elements for polyconvexity [3] with the EAS method are presented. It is shown that this combination provides a promising framework for novel finite element methods.
Competitive evaporation of multiple sessile droplets

An asymptotic model is derived for the competitive diffusion-limited evaporation of multiple thin sessile droplets under the assumption that the droplets are well separated. Exact solutions of the model are obtained for a pair of and for a polygonal array of identical droplets, and the model is found to perform well even outside its formal range of validity, up to and including the limit of touching droplets. The shielding effect of droplets on each other is demonstrated, and the model is used to investigate the effect of this shielding on droplet evolutions and lifetimes, as well as on the coffee-ring effect. The theoretical predictions of the model are found to be in good agreement with recent experimental results for seven relatively closely spaced droplets, suggesting that the model could be a useful tool for studying a wide range of other droplet configurations.
Bilinear Coagulation Equations.

We consider coagulation equations of Smoluchowski or Flory type where the total merge rate has a bilinear form $\pi(y)\cdot A\pi(x)$ for a vector of conserved quantities $\pi$, generalising the multiplicative kernel. For these kernels, a gelation transition occurs at a finite time $t_\mathrm{g}\in (0,\infty)$, which can be given exactly in terms of an eigenvalue problem in finite dimensions. We prove a hydrodynamic limit for a stochastic coagulant, including a corresponding phase transition for the largest particle, and exploit a coupling to random graphs to extend analysis of the limiting process beyond the gelation time.
Model-Independent Probes of Cosmology & Gravitation

Cosmology & Gravitation are the fundamental studies in understanding the physics of the universe that we reside in. The approach in achieving the knowledge of the physical laws which govern our universe, is via the observations of the dynamics, geometries, and evolution of the astrophysical structures within it. Recent cosmological observations have fitted well to a cosmological model known as ΛCDM; where our universe’s energy content is dominated a cosmological constant (Λ) and Cold Dark Matter (CDM). The ΛCDM model is based with gravity described by Einstein’s theory of General Relativity (GR); where GR also provides the best description of gravity on all scales. However, the ΛCDM plus GR model requires a cold, non-baryonic, non-visible CDM component, and DE to fit the cosmological data. At present, there is no decisive detection of DM leaving an open window for Modified Gravity (MG) theories attempting to explain data without the inclusion of DM; and the ΛCDM model contains loose constraints on the Epoch of Reionization (EoR), the epoch at which the first galaxies and Super Massive Black Holes (SMBH) began to form. This thesis consists of model-independent probes of cosmology & gravitation. Part of this thesis involves searching for high redshift, z ≥ 6.5 quasars, with the VISTA Kilo-degree INfrared Galaxy (VIKING), where we expand on the search criteria used by Findlay et al. (2012) and Venemans et al. (2013), by applying various specific cut methods, resulting in an extended search for these high redshift quasars within the VISTA Science Archive (VSA) database. These quasars can be used as cosmological probes of the EoR by constraining the redshift at which EoR begun, and the formation & evolution of the first galaxies and SMBHs. Another part of this thesis is the prospects of testing gravity in very low acceleration regimes via Wide Binary (WB) stellar systems, with separations & 3 kAU. These WB systems can achieve low accelerations, on scales . 10−10 m s−2, which is comparable to the value where galaxy rotation curves flattens due to DM or a MG. Thus, WBs can probe these low acceleration regimes without the presence of DM, hence making them ‘clean’ and powerful probes of gravity. Our work consists of simulating a large sample of random orbits in various MG models, and predict the observed relative velocities and projected separations, comparing Newtonian prediction against other
Effect of Xiexin Decoction on early diabetic nephropathy in diabetic rats

Objective To investigate the effect of Xiexin Decoction(XXD) on the early diabetic nephropathy(DN) of diabetic rats induced by high-fat diet with injection of streptozotocin(STZ). MethodsMale Sprague-Dawley rats were divided into two groups and fed with normal pellet diet(NPD) or high-fat diet(HFD),respectively,for a period of four weeks and then HFD-fed rats were ip injected with STZ.The diabetic rats were divided into three groups: model group,XXD group,and metformin group.After 13-weeks ig administration,fasting blood glucose(FBG),glycated hemoglobin(HbAlc),blood lipids(TG and TC),serum insulin(INS),renal function,kidney index,albumin in urine,and the renal histology and ultrastructure were observed.Results Compared with the model group,XXD reduced the levels of water intake,food consumption,urine volume,HbAlc,insulin resistance index(IRI),creatinine clearance rate(CCr),albumin in urine and blood lipids(P0.05 or P0.01) and decreased the incrassation of the glomerular basement membrane,and the change of foot process fusion.Conclusion XXD could protect the kidney in rats with experimental early DN.The nephroprotection of XXD may be related to the decrease in blood lipids and HbAlc and improvement in insulin resistance.
