The Two Scaling Regimes of the Thermodynamic Uncertainty Relation for the KPZ-Equation

We investigate the thermodynamic uncertainty relation for the $$(1+1)$$ ( 1 + 1 ) dimensional Kardar–Parisi–Zhang (KPZ) equation on a finite spatial interval. In particular, we extend the results for small coupling strengths obtained previously to large values of the coupling parameter. It will be shown that, due to the scaling behavior of the KPZ equation, the thermodynamic uncertainty relation (TUR) product displays two distinct regimes which are separated by a critical value of an effective coupling parameter. The asymptotic behavior below and above the critical threshold is explored analytically. For small coupling, we determine this product perturbatively including the fourth order; for strong coupling we employ a dynamical renormalization group approach. Whereas the TUR product approaches a value of 5 in the weak coupling limit, it asymptotically displays a linear increase with the coupling parameter for strong couplings. The analytical results are then compared to direct numerical simulations of the KPZ equation showing convincing agreement.

Pengaruh Display Produk Dan Promosi Terhadap Keputusan Pembelian Konsumen Pada Buku Terbitan Mizan (Studi Kasus Toko Buku Gunung Agung BSD)

The purpose of this study was to determine how much influence the product display and promotion partially on consumer purchasing decisions on books published by Mizan at Gunung Agung BSD Tangerang bookstore and to find out how much influence the product displays and promotions simultaneously on consumer purchasing decisions on books published by Mizan at the Gunung Agung BSD Tangerang bookstore. This research is causality with quantitative approach. The population in this study is Mizan's book customers at the Gunung Agung BSD bookstore Tangerang with convenience sampling technique obtained samples of 69 respondents. Data analysis techniques used in this study are: data quality tests including validity and reliability, the classic assumption test of normality, multicollinearity, heterocendatisity, regression analysis that is multiple regression, partial t, simultaneous F and coefficient of determination. The results of the study are as follows: (1) The results of first hypothesis that is no significant influence between product displays on consumer purchasing decisions, (2) The results of second hypothesis that is a positive and significant effect between promotions on decisions consumer purchases, and (3) The results of third hypothesis, namely product display and promotion together have a positive and significant effect on consumer purchasing decisions.

One Pot Synthesis, Surface and Magnetic Properties of Cu2O/Cu and Cu2O/CuO Nanocomposites

A series of copper-based systems containing two different nanocomposites (Cu2O/CuO and Cu2O/Cu) was synthesized by the egg white assisted auto-combustion route. This method was distinguished by the simplicity of its steps, low cost, one-pot synthesis process at low temperature and, short time. The characterization of the as prepared nanocomposites was carried out by using X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Scanning electron microscope (SEM) and transmission electron micrograph (TEM), Energy dispersive spectrometry (EDS) techniques. Surface and magnetic properties of the obtained systems were determined by using N2 adsorption/desorption isotherms at 77 K and the vibrating sample magnetometer (VSM) technique. XRD results confirmed the formation of Cu2O/CuO and Cu2O/Cu nanocomposites with different ratios of well crystalline CuO, Cu2O, and Cu phases. FTIR results of the combusted product displays the presence of both CuO and Cu2O, respectively. SEM/EDS and TEM results confirm the formation of a porous nanocomposite containing Cu, O, and C elements. The change in concentration of the oxygen vacancies at the surface or interface of both Cu2O/CuO and Cu2O/Cu nanoparticles resulted in different changes in their magnetization. Based on this study, it is possible to obtain nanocomposite-based copper with multiple valances by a simple and inexpensive route which can be suitable for the fabrication of different transition metal composites.

Prediksi Pola Tata Letak Produk untuk Strategi Penjualan Menggunakan Algoritma Apriori

Data mining is a term used to describe the discovery of knowledge in databases. Data mining is a process that uses statistical techniques, mathematics, artificial intelligence, and maching learning to extract and identify useful information and related knowledge from large databases. One of the data mining methods is the association rule by analyzing a sales transaction at the 212 mart latsitarda Kisaran store. Sales transaction analysis aims to design a sales strategy. To design an effective sales or marketing strategy. In addition, the use of this analytical technique can also find changing patterns of products that are often purchased together or products that tend to appear together in a transaction from transaction data which are generally large in size. Store 212 mart latsitarda Kisaran can then use this pattern to place frequently purchased products into a contiguous area. Designing product displays in catalogs, designing product package sales, and so on using data mining concepts (a priori algorithm approach) so that they can analyze buyer behavior. Keywords: Data Mining; Product Layout Pattern; Apriori Algorithm Abstrak: Data Mining adalah suatu istilah yang digunakan untuk memguraikan penemuan pengetahuan didalam database. Data Mining adalah proses yang menggunakan teknik statistik, matematika, kecerdasan buatan, dan maching learning untuk mengestraksi dan mengindentifikasi informasi yang bermanfaat dan pengetahuan yang terkait dari berbagai database besar. Salah satu metode data mining adalah aturan asosiasi dengan melakukan analisis suatu transaksi penjualan pada toko 212 mart latsitarda Kisaran. Analisis transaksi penjualan bertujuan untuk merancang strategi penjualan. Untuk merancang strategi penjualan atau pemasaran yang efektif. Selain itu, penggunaaan teknik analisis ini juga dapat menemukan pola berubah produk-produk yang sering dibeli bersamaan atau produk yang cenderung muncul bersaama dalam sebuah transaksi dari data transaksi yang pada umumnya berukuran besar. Toko 212 mart latsitarda Kisaran lalu dapat menggunakan pola ini untuk menempatkan produk yang sering dibeli kedalam sebuah area yang berdekatan. Merancang tampilan produk di katalok, merancang penjualan paket produk, dan sebagainya dengan menggunakan konsep data mining (pendekatan algoritma apriori) sehingga dapat menganalisis prilaku pembeli.

KÖP DEN HÄR! How IKEA North York visually communicates persuasive messages to shoppers

This Major Research Paper (MRP) closely examines IKEA North York as an organization that constructs visual messages in their retail environments and persuasively communicates to its shoppers through visuals in product displays, including display structure, signage, and location, to encourage consumer behaviour and impact purchasing decisions. Three product displays were closely examined in the “Cookshop & Tableware” department of IKEA North York’s Market Hall through a thorough visual analysis of each product display utilizing four guiding concepts derived from document design and visual communication (information hierarchy, white space, colour, and ambience) and examining corresponding consumer behaviour through on-site observations. Preliminary conclusions state that while IKEA North York effectively designs its retail space on a 2-dimensional plane, further consideration needs to be taken when designing the 3-dimensional nature of the store environment. This research could be furthered through the inclusion of a broader data set and wider criteria for examination.
