Digital Mobility Platforms and Ecosystems

To support the digital transformation in the area of Smart Mobility and Smart City, the TUM Living Lab Connected Mobility (TUM LLCM) research project was initiated, funded by the Bavarian Ministry of Economic Affairs and Media, Energy and Technology (StMWi) through the Center Digitisation.Bavaria, an initiative of the Bavarian State Government. The project bundles the relevant research, implementation, and innovation skills of the Technical University of Munich in the fields of informatic and transport research. The research project contributes to the design and implementation of open, provider-independent digital mobility platforms. The actual commercial implementation of these platforms is carried out by leading digital providers based on the market requirements of customer-oriented mobility solutions. Another significant achievement of the project is the networking of already established and currently arising mobility providers, service providers, developers and users on a personal, organizational and technical level. Thus, the project contributes to the establishment of a mobility ecosystem, which is necessary for the success of the mobility platform. Thereby, smaller companies and start-ups are enabled to develop their own digital mobility services with reduced financial, organizational and technical effort. The TUM Living Lab Connected Mobility thus simplifies and accelerates the exchange regarding the development of digital mobility services between university, industry and end-users. The university contributes to this digital ecosystem with current research findings from key areas of digital mobility platforms such as data analysis, app development, service monitoring, platform governance and efficient and legally secure integration of other partners. It draws on the established cooperation between TUM, the local industry, but also the local start-up scene to account for practical demands in the field of digital mobility platforms from the beginning. Furthermore, the dialogue with local and regional institutions for traffic management and operations (administrations, associations, system and service operators) places a significant role in the development processes of the Living Lab Connected Mobility.
Hybrid circuits for the CMS tracker upgrade frontend electronics

The upgrade of the CMS tracker at the HL-LHC requires the design of new front-end modules to cope with the increased luminosity and to implement L1 trigger functionality. The new modules under development are based on high density hybrid circuits with new flip-chip front-end ASIC, and are wire bonded to strip sensors and connected to a service board for the data transmission. The suitability of different substrate technologies considered for the design of the hybrids is discussed, aiming for a cost effective and reliable manufacturability of the CMS tracker modules.
The architecture design of a 2mW 18-bit high speed weight voltage type DAC based on dual weight resistance chain

At present, the architecture of a digital-to-analog converter (DAC) in essence is based on the weight current, and the average value of its D/A signal current increases in geometric series according to its digital signal bits increase, which is 2n−1 times of its least weight current. But for a dual weight resistance chain type DAC, by using the weight voltage manner to D/A conversion, the D/A signal current is fixed to chain current Icha; it is only 1/2n−1 order of magnitude of the average signal current value of the weight current type DAC. Its principle is: n pairs dual weight resistances form a resistance chain, which ensures the constancy of the chain current; if digital signals control the total weight resistance from the output point to the zero potential point, that could directly control the total weight voltage of the output point, so that the digital signals directly turn into a sum of the weight voltage signals; thus the following goals are realized: (1) the total current is less than 200 μA; (2) the total power consumption is less than 2 mW; (3) an 18-bit conversion can be realized by adopting a multi-grade structure; (4) the chip area is one order of magnitude smaller than the subsection current-steering type DAC; (5) the error depends only on the error of the unit resistance, so it is smaller than the error of the subsection current-steering type DAC; (6) the conversion time is only one action time of switch on or off, so its speed is not lower than the present DAC.
Facile synthesis of ZnO nanowires on FTO glass for dye-sensitized solar cells

Long and well-aligned ZnO nanowires were hydrothermally synthesized on FTO glass based on a ZnO seed layer which was prepared by spin-coating and annealing techniques. The effect of the growth solution refreshment on the morphology of ZnO nanowires was investigated and the possible mechanism was discussed. After refreshing the growth solution for 5 cycles, ZnO nanowires of ∼ 120 nm in diameter and ∼ 20 μm in length were obtained. The prepared ZnO nanowires were used as photoelectrodes in dye-sensitized solar cells (DSSCs), showing excellent photovoltaic performance. With the increase of growth cycles of ZnO nanowires, the photocurrent of DSSCs increased obviously due to the increased dye loading on the surface of ZnO nanowires. The results indicated that the long and well-aligned ZnO nanowires are promising for DSSCs application.
Design of an LDO with capacitor multiplier

This paper presents a low quiescent current, highly stable low-drop out (LDO) regulator. In order to reduce capacitor value and control frequency response peak, capacitor multipliers are adopted in the compensation circuit with mathematic calculations. The phase margin is adequate when the load current is 0.1 or 150 mA. Fabricated in an XFAB 0.6 μm CMOS process, the LDO produces 12.2 mV (0.7%) overshoot voltage while the current changes at 770 mA/100 μs with a capacitor load of 10 μF.
Performance comparison of radiation-hardened layout techniques

Total ionizing dose (TID) effect and single event effect (SEE) from space may cause serious effects on bulk silicon and silicon on insulator (SOI) devices, so designers must pay much attention to these bad effects to achieve better performance. This paper presents different radiation-hardened layout techniques to mitigate TID and SEE effect on bulk silicon and SOI device and their corresponding advantages and disadvantages are studied in detail. Under 0.13 μm bulk silicon and SOI process technology, performance comparisons of two different kinds of DFF circuit are made, of which one kind is only hardened in layout (protection ring for bulk silicon DFF, T-gate for SOI DFF), while the other kind is also hardened in schematic such as DICE structure. The result shows that static power and leakage of SOI DFF is lower than that of bulk silicon DFF, while SOI DFF with T-gate is a little slower than bulk silicon DFF with protection ring, which will provide useful guidance for radiation-hardened circuit and layout design.
A 8.75–11.2-GHz, low phase noise fractional-N synthesizer for 802.11a/b/g zero-IF transceiver

An ultra broadband fractional-N frequency synthesizer for 802.11a/b/g zero-IF transceiver application is presented. The mathematical models for the behavior of the synthesizer's spur and phase noise are analyzed, and the optimization methodology is proposed. Measurement results exhibits that the frequency synthesizer's integrated phase noise is less than 1° (1 kHz to 100 MHz) with a 4.375 GHz carrier (after divide-by-2), and the reference frequency spur is below −60 dBc operating with a 33 MHz reference clock. The frequency synthesizer is fabricated on a standard 0.13 μm RF CMOS process and consumes 39.6 mW from a 1.2 V supply voltage.
Vortex molecule and i-soliton studies in multilayer cuprate superconductors

We observed two dissipation peaks in the field cooled AC susceptibility measurements on aligned multilayered cuprate Superconductor, (Cu,C)Ba2Ca2Cu3Oy[(Cu,C)-1223], and demonstrated that it is the direct experimental indication of the two-component vortex matter in the multilayered cuprates. We propose that, the second loss peak at lower temperature is due to the additional degree of freedom of the rotation of ‘vortex molecule’ composed of two fractional vortices, originated at two components, mediated by an i-soliton bond. To probe the dynamics of this vortex molecule, we measured frequency dependence of AC susceptibility response on aligned crystallites of (Cu,C)-1223 at different temperatures and DC fields. In second peak region, it gives resonance peak. The observed frequency dependence patterns of x"(T), for 0.5 T HDC, are rescaled with the resonating frequencies and show tail at low frequency region indicating that the dissipation is due to rotation and twisting of vortex molecule. The temperature dependence of the average relaxation time shows that the vortex molecule rotation/twisting glass state follow critical slowing down process.
The importance of hydrodynamics and mechanical action in fabric washing

Washing fabrics is a ubiquitous process that has been found to have been common even in early civilisations. The process can be performed by hand or with the aid of a washing machine, giving rise to a wide range of wash conditions. Although this process is very common the mechanisms involved are poorly understood, but are thought to involve chemical, mechanical and hydrodynamic inputs. The main aim of this project is to test whether these inputs can be used to improve the efficiency of cleaning fabrics at lower temperatures, and to better understand the mechanisms involved in these individual actions. The cleaning of polyester and cotton fabrics soiled with artificial sebum has been investigated with 20 °C, 40 °C and 60 °C wash solutions. Fabrics have been cleaned with a model surfactant system consisting of Linear Alkylbenzene Sulfonate (LAS) at 0.1 times and twice the Critical Micelle Concentration (CMC), and results compared to water. Bespoke rigs to simulate rubbing, stretching and flow have been optimised and methods developed for cleaning and analysis of fabrics. Cleaning has been characterised by mass change, colour change and resistance change. Mass change gives an indication of the overall removal, whereas colour gives an analytical measure of the difference in the appearance of the fabrics, and change in resistance to flow of water through the fabric shows how much sebum has been removed from the pores. Additional analysis has been completed on the fabrics including FTIR, mass per unit area, SEM and zeta potential measurements. Removal was highest when the fabric was washed at 60 °C with a high concentration of surfactant. Soaking alone removed some of the mass, but this increased when mechanical action was also used. Of the mechanical actions, rubbing was found to be the most effective under most conditions. On the whole, cleaning was more effective at 40 °C than 20 °C, and a higher concentration of surfactant aided removal of soil to a greater extent that at a lower concentration or with water alone. However, some exceptions to these trends have been identified.
Perspectives of use of agricultural drones in Uzbekistan

In this article, use of drones for agricultural purposes in Uzbekistan are depicted. Amid security reasons of drone usage, Uzbekistan is adopting innovative technologies of Unmanned Aerial Vehicles (UAVs) as local research institutions and state agencies are embracing ease of use, accuracy and multi-functionality of UAVs. Increasing concerns of water scarcity, increased aridity and declining yields, Uzbek agricultural industry is showing vivid interest for the use of drones in agricultural management, yet observing regulatory and technical challenges.
VOLTAGE PROFILE IMPROVEMENT USING FACTS DEVICES

This paper addresses improving the voltage stability limit of power flow between two different regions in an electric power system using the Fixed capacitor Thyristor controlled reactor (FC-TCR) or Static Var Compensator (SVC) and SSSC. Modelling and simulation of Static Var Compensator (SVC) for power system stability enhancement and improvement of power transfer capability have been presented in this paper. First, power flow results are obtained and then power (real and reactive power) profiles have been studied for an uncompensated system and then compared with the results obtained after compensating the system using the above-mentioned SVC device. The simulation results demonstrate the performance of the system in improving the power profile and thereby voltage stability of the same. All simulations have been carried out in MATLAB/SIMULINK environment. A methodology for determining the power flow margin is simply briefed.
Survey of physical modelling in Resistive Plate Chambers

Apparently simple detectors, Resistive Plate Chambers actually incorporate a range of physical situations somewhat more complex than those found in most other gaseous detectors. These include the interplay between materials with different electrical characteristics, space-charge dominated avalanches evolving in very high electric fields and the propagation of fast signals on heterogeneous multiconductor transmission lines. In this article the state-of-the-art of physical modelling of many of these aspects is reviewed and sometimes expanded, while aspects still requiring further work are highlighted.
Arterial pressure measurement: Is the envelope curve of the oscillometric method influenced by arterial stiffness?

Measurement of peripheral arterial pressure using the oscillometric method is commonly used by professionals as well as by patients in their homes. This non invasive automatic method is fast, efficient and the required equipment is affordable with a low cost. The measurement method consists of obtaining parameters from a calibrated decreasing curve that is modulated by heart beats witch appear when arterial pressure reaches the cuff pressure. Diastolic, mean and systolic pressures are obtained calculating particular instants from the heart beats envelope curve. In this article we analyze the envelope of this amplified curve to find out if its morphology is related to arterial stiffness in patients. We found, in 33 volunteers, that the envelope waveform width correlates to systolic pressure (r=0.4, p<0.05), to pulse pressure (r=0.6, p<0.05) and to pulse pressure normalized to systolic pressure (r=0.6, p<0.05). We believe that the morphology of the heart beats envelope curve obtained with the oscillometric method for peripheral pressure measurement depends on arterial stiffness and can be used to enhance pressure measurements.
Equation of states and melting temperatures of diamond cubic and zincblende semiconductors: pressure dependence

The pressure dependence of the melting temperatures of tetrahedrally coordinated semiconductors are studied using the equation of states derived from the statistical moment method, in comparison with those of the normal metals. Using the general expressions of the limiting temperatures Tm, we calculate the ‘melting’ temperatures of the semiconductor crystals and normal metals as a function of the hydrostatic pressure. The physical origins for the inverse pressure dependence of Tm observed for tetrahedrally coordinated semiconductors are also discussed.
A single channel, 6-bit 230-MS/s asynchronous SAR ADC based on 2 bits/stage

This paper proposes a single channel, 6-bit 230-MS/s asynchronous successive approximation register analog-to-digital converter (ADC) in an SMIC 65 nm CMOS technology. Through adopting the modified 2 bits/stage asynchronous control logic, the presented ADC actualizes a peak 40.90-dB spurious-free dynamic range and 29.05-dB signal-to-noise and distortion ratio at 230-MS/s sampling rate. Utilizing the dynamic comparator without the preamplifier, this work attains low-power design with only 0.93 mW power consumption and accomplishes a figure of merit of 174.67 fJ/step at 1 V supply voltage.

Performance enhancement of pentacene-based organic field-effect transistor by inserting a WO3 buffer layer

The pentacene-based organic field effect transistor (OFET) with a thin transition metal oxide (WO3) layer between pentacene and metal (Al) source/drain electrodes was fabricated. Compared with conventional OFET with only metal Al source/drain electrodes, the introduction of the WO3 buffer layer leads to the device performance enhancement. The effective field-effect mobility and threshold voltage are improved to 1.90 cm2/(V·s) and 13 V, respectively. The performance improvements are attributed to the decrease of the interface energy barrier and the contact resistance. The results indicate that it is an effective approach to improve the OFET performance by using a WO3 buffer layer.
Enhancement of Cluster-based Routing Protocol with Parameters Consideration in Wireless Sensor Network

A wireless sensor network (WSN) consists of large number of battery operated sensor nodes which are generally deployed in different environments. These sensor nodes have limited energy to sense, process and transmit information. Therefore, there is a need to design an energy efficient routing protocol to extend the lifetime of a WSN. Low Energy Adaptive Clustering Hierarchy (LEACH) protocols are considered to optimize the energy consumption. In this paper, a cluster based routing protocol called Enhancement of Cluster-based Routing Protocol with Parameter Consideration (ECRP-PC) is proposed, in which an assistant Cluster Head called Vice Cluster Head (VCH) is introduced in addition to Cluster Head (CH). In a cluster, the node with the highest residual energy among all nodes is selected as the CH, and the node with second highest residual energy is selected by the CH as the VCH when the cluster head distance is longer than the specified distance. VCH will serve as a backup node of the CH. The selected VCH will be in a sleep mode as long as the energy of CH is above a threshold, and it will become active when the energy of CH is below a threshold. According to the results, the proposed ECRP-PC protocol is able to increase the average lifetime of nodes up to 56% compared to the original LEACH.
Classification results on purely electric or magnetic perfect fluids

Non-conformally flat, non-vacuum perfect fluid models for which the magnetic, resp. electric, part of the Weyl tensor w.r. t. the fluid congruence vanishes, are called purely electric (PE), resp. purely magnetic (PM), perfect fluids. Their Petrov type is necessarily I or D. They are of particular interest, since the electric part is the relativistic generalization of the tidal tensor in Newtonian theory, whereas the magnetic part has no Newtonian analogue. A survey of recent classification results is presented, with focus on Petrov type D and on the Petrov type I non-accelerating subclass. Important known universe models are naturally embedded in the analysis, while new and physically interesting PE and PM families emerge.
Learning Process Oriented Teaching Quality Improvement

In order to get targeted improving strategies for better teaching quality, it is necessary to establish learning data model for specific courses covering the whole learning process, and accurate and stable student performance classification model accordingly. Drawing on existing learning data analysis of online teaching, this paper proposes process oriented learning feature model, student performance classification method, and corresponding improving strategies analysis. With learning data from “Computer Network Fundamentals” course, in which combined online and offline teaching methods are used, learning process oriented feature model are defined using correlation analysis and clustering methods; improved Support Vector Machine (SVM) classification method with grid search optimization are proposed to get optimized student performance classification model, which gains 8% improvement on the accuracy compared to classified SVM model. Based on experiments, the accuracy of optimized classification model is 90%, with 6% false positive rate and 11% false negatives rate, which are reasonable and shows the accuracy and stability of our model. The improving strategies analysis for different students classification are also given, which can provide strong support for teaching quality improvement.
Delft University of Technology Long-term performance of marine structures in the Netherlands-validation of predictive models for chloride ingress

For many concrete infrastructural works a service life of 80, 100 or 200 years is required. To convince owners and authorities that these requirements can be met probability-based models for service life predictions have been developed. These models are based on theoretical and experimental laboratory studies. Many of these models focus on the probability of chloride-induced rebar corrosion. For a check of the reliability of one of these models, i.e. the DURACRETE model, predicted chloride profiles have been compared with chloride profiles measured in five marine concrete structures. Lessons learned from these existing structures in view of the reliability of numerical service life predictions are presented in this paper.
