Abstract:
Abstract Random and systematic errors affect navigation satellite observations on both pseudo-range and carrier phase. These errors are originated at satellites, propagation path and receivers. This study focuses on the GNSS receiver internal delay determination resulting from the receiver’s electronics circuit. The characterisation of the delay in the GNSS geodetic receivers is essential to enhance the accuracy for the time transfer and time comparisons as part of GNSS integrity chain determinations. The purpose of GNSS receiver internal delay at the National Institute of Metrology (Thailand), NIMT, is to estimate the characteristics and performances of the GNSS geodetic receiver used for international time comparisons. The experiments are simultaneously observed GNSS satellites by a GPS and a GNSS receivers and two separate antennas with short baseline (around 6 metres), where both receivers are connected to the identical external caesium frequency standard maintained as time and frequency standard of Thailand. The GPS receiver is well-defined for its receiver internal delay on the pseudo-range observation of C1, through comparisons using an internationally recognised method, while the geodetic GNSS receiver is to be defined on its receiver internal delay. These experiment observations started from 26 December 2017 to 17 January 2018 at NIMT, Pathumthani, Thailand. The determined unknowns are receiver position, receiver clock offset, tropospheric delay through the geodetic technique of static Precise Point Positioning observations with Bernese GNSS software version 5.2. Later the receiver internal delay of NIMT is computed and analysed. The receiver internal delay on GPS C1 code is successfully characterised, resulted as 346.0 nanoseconds as of this experiment.

Abstract:
Abstract Transfer printing, as an important assembly technique, has attracted much attention due to its valuable merits to develop novel forms of electronics such as stretchable inorganic electronics requiring the heterogeneous integration of inorganic materials with soft elastomers. Here, we report on a laser-driven programmable non-contact transfer printing technique via a simple yet robust design of active elastomeric microstructured stamp that features cavities filled with air and embedded under the contacting surface, a micro-patterned surface membrane that encapsulates the air cavities and a metal layer on the inner-cavity surfaces serving as the laser-absorbing layer. The micro-patterned surface membrane can be inflated dynamically to control the interfacial adhesion, which can be switched from strong state to weak state by more than three orders of magnitude by local laser heating of the air in the cavity with a temperature increase below 100°C. Theoretical and experimental studies reveal the fundamental aspects of the design and fabrication of the active elastomeric microstructured stamp and the operation of non-contact transfer printing. Demonstrations in the programmable transfer printing of micro-scale silicon platelets and micro-scale LED chips onto various challenging receivers illustrate the extraordinary capabilities for deterministic assembly that are difficult to address by existing printing schemes, thereby creating engineering opportunities in areas requiring the heterogeneous integration of diverse materials such as curvilinear electronics and MicroLED displays.

Abstract:
The antenna array technology, especially the spaced-time array processing (STAP), is one of the effective methods used in Global Navigation Satellite System (GNSS) receivers to refrain the power of jamming and enhance the performance of receivers in the circumstance of interference. However, biases induced to the receiver because of many reasons, including characteristic of antennas, front-end channel electronics, and space-time filtering, are extremely harmful to the high precise positioning of receivers. Although plenty of works have been done to calibrate the antenna and to mitigate these biases, achieving a good performance of antijamming, high accuracy, and low complexity at the same time still remains challenging. Different from existing works, this paper leverages the characteristic of GNSS signal’s Doppler frequency in STAP, which is proven to remain unbiased to solve the problem, even when the nonideal antennas are used and the interference circumstance changes. Since the integration of frequency is carrier phase, the unbiased Doppler frequency leads to an accurate estimation of carrier phase which can be used to calibrate the antenna array without extra apparatus or complicating algorithms. Therefore, a simple Doppler-aid strategy may be developed in the future to solve the difficulty of STAP bias mitigation.

Abstract:
The paper describes the influence of power electronics, energy processing, and emergency radio systems (ERS) immunity testing on onboard aircraft equipment and ground stations providing air traffic services. The implementation of next-generation power electronics introduces potential hazards for the safety and reliability of aircraft systems, especially the interferences from power electronics with high-power processing. The paper focuses on clearly identifying, experimentally verifying, and quantifiably measuring the effects of power electronics processing using switching modes versus the electromagnetic compatibility (EMC) of emergency radio systems with electromagnetic interference (EMI). EMI can be very critical when switching power radios utilize backup receivers, which are used as aircraft backup systems or airport last-resort systems. The switching power electronics process produces interfering electromagnetic energy to create problems with onboard aircraft radios or instrument landing system (ILS) avionics services. Analyses demonstrate significant threats and risks resulting from interferences between radio and power electronics in airborne systems. Results demonstrate the impact of interferences on intermediate-frequency processing, namely, for very high frequency (VHF) radios. The paper also describes the methodology of testing radio immunity against both weak and strong signals in accordance with recent aviation standards and guidance for military radio communication systems in the VHF band.

Abstract:
A superheterodyne receiver is a type of device universally used in a variety of electronics and information systems. Fault detection and diagnosis for superheterodyne receivers are therefore of critical importance, especially in noise environments. A general purpose fault detection and diagnosis scheme based on observers and residual error analysis was proposed in this study. In the scheme, two generalized regression neural networks (GRNNs) are utilized for fault detection, with one as an observer and the other as an adaptive threshold generator; faults are detected by comparing the residual error and the threshold. Then, time and frequency domain features are extracted from the residual error for diagnosis. A probabilistic neural network (PNN) acts as a classifier to realize the fault diagnosis. Finally, to mimic electromagnetic environments with noise interference, simulation model under different fault conditions with noise interferences is established to test the effectiveness and robustness of the proposed fault detection and diagnosis scheme. Results of the simulation experiments proved that the presented method is effective and robust in simulated electromagnetic environments.

Abstract:
The superheterodyne receiver is a typical device widely used in electronics and information systems. Thus effective performance assessment and prediction for superheterodyne receiver are necessary for its preventative maintenance. A scheme of performance assessment and prediction based on Mahalanobis distance and time sequence analysis is proposed in this paper. First, a state observer based on radial basis function (RBF) neural network is designed to monitor the superheterodyne receiver and generate the estimated output. The residual error can be calculated by the actual and estimated output. Second, time-domain features of the residual error are then extracted; after that, the Mahalanobis distance measurement is utilized to obtain the health confidence value which represents the performance assessment result of the most recent state. Furthermore, an Elman neural network based time sequence analysis approach is adopted to forecast the future performance of the superheterodyne receiver system. The results of simulation experiments demonstrate the robustness and effectiveness of the proposed performance assessment and prediction method.

Abstract:
Electronic Support Measures (ESM) receivers exist that are capable of detecting the transmissions from radar emitters in a robust and reliable manner. Typically, the receiver operator wishes to detect the transmitted signals from a known set of emitters as quickly as possible. To achieve this, a schedule is created that dictates the order in which the receiver will search for the various emitters. Techniques exist for predicting the maximum time to intercept between a receiver and an emitter, but they only work from known scheduling parameters. The quantity of emitters and the density of their signals typically prevents a naive approach to generating the schedule. The purpose of this thesis was to generate scanning receiver schedules that minimize the maximum time to intercept for a set of scanning emitters. Genetic algorithms and the use of pulse train theory were combined to generate the schedules in an automated fashion. The genetic algorithm consistently produced ESM receiver schedules that used duration values for each frequency band that were near the largest scan rate of all the emitters in each band. This was an unexpected result and demonstrated that the minimization of the maximum intercept time for a set of emitters can be accomplished using the maximum scan values. A new scheduling algorithm was created that utilized the maximum scan values. It generated ESM receiver schedules that were equivalent to the best schedules produced by the genetic algorithm scheduler, and produced them with much less computational effort.

Abstract:

One of the main challenges posed by 4G wireless communication systems is achieving flexible, programmable multi-standard radio transceivers with maximum hardware share amongst different standards at a minimum power consumption. Evaluating the feasibility and performance of different multi-standard/multi-band radio solutions at an early stage, i.e. system level, is key for succeeding in surmounting this challenge. This entails formulation of the transceiver budget for several RF architectures and frequency plans with different degrees of hardware sharing. This task is complicated by the fact that transceiver blocks can have different implementations that lead to different performances. The tools that are available for use at present have only analysis capabilities or address only one standard and/or receiver architecture at a time.

In the belief that a new approach to this problem is necessary, the work that has led to this thesis proposes a novel methodology that automates the design-space exploration of integrated multi-standard wireless radio receivers. This methodology has been implemented in a multi-standard RF Transceiver Architecture Comparison Tool, TACT. TACT helps surmounting many of the challenges faced by RF system designers targeting multi-standard/multi-band radio receivers.

The goal of the algorithms TACT is built upon is to find a multi-standard receiver frequency plan and budget that meets or exceeds the specifications of the addressed wireless standards while keeping the requirements of each of the receiver blocks as relaxed as possible. TACT offers RF engineers a deep insight into the receiver behavior at a very early stage of the design flow. It models the impact of critical circuit non-idealities using a high level of abstraction. This reduces the number of design iterations and, thus, the time-to-market of the solution. The reuse of already available intellectual property (IP) blocks is also considered in TACT, what can result in a significant cost reduction of the receiver implementation.

A case study of a WCDMA/WLAN multi-standard receiver designed using TACT is presented in order to illustrate the capabilities of the proposed techniques.

Abstract:
Optical interconnects have attracted great interest as data rates continue to increase. When compared with their electrical counterparts, optical interconnects have significant advantages in terms of crosstalk, bandwidth, distance, and latency. Many applications stand to benefit from low-cost, high-speed integrated optical transceivers with single-channel gigabit data rates. As in the case of RF wireless designs, using CMOS technology is of special interest due to the potential of lower cost and higher integration. The analog frontend is a key component in optical receivers due to its importance in bridging the optical and electrical signal domains. In this work, we present a 10 Gb/s optical receiver frontend designed and fabricated in ST’s 90 nm CMOS technology. The receiver contains a transimpedance (pre)amplifier (TIA), and limiting amplifier (LA), and an output buffer (OB). The TIA demonstrates a transimpedance gain of 61.9 dB Ohm and a bandwidth of 7.4 GHz, trading off noise and ISI considerations. The single-ended design utilizes 1.5 mW of power from a 1.0 V supply. The LA demonstrates a voltage gain of 21 dB and a bandwidth extended to 10 GHz using inductive peaking. The differential design utilizes 3.9 mW of power from a 1.0 V supply. Finally, the output buffer is capable of driving large output voltage swings to 50 Ohm on-chip terminations. In order to test the receiver, a PCB and testing strategy is co-designed with the chip. Details concerning the various design decisions, tradeoffs, are discussed in this thesis. Experimental results of a fabricated device are presented under ideal and practical system levels, with data rates up to 8.5 Gb/s.

En comparaison avec leurs contre-parties électriques, les interconnexions optiques ont des avantages significatifs en termes d’interférence, largeur de bande, distance, et latence. En raison de ces avantages, beaucoup d’applications se tiennent pour des bénéfices des récepteurs optiques intégrés peu coûteux et à grande vitesse.Le devant analogue dans les récepteurs optiques est une composante clé, son importance en jetant un pont sur les domaines de signal optique et électrique. Dans ce travail, nous présentons un récepteur optique 10 Gb/s conçu et fabriqué en technologie CMOS à 90 nanomètre. Le récepteur contient un (pré)amplificateur de transimpedance (TIA), un l’amplificateur limiter (LA), et un amortisseur de rendement (OB). Le TIA démontre un gain de transimpedance de 61.9 dB Ohm et d’une largeur de bande de 7.4 gigahertz, en balançant les considérations de bruit et de l’inteférance des symboles. La conception utilise 1.5 mW de puissance à un tension de 1.0 V. La LA démontre un gain de 21 dB et une largeur de bande prolongée à 10 gigahertz utilisant une pointe inductif. La conception différentielle utilise 3.9 mW de puissance à un tension de 1.0 V. En conclusion, l’amortisseur de rendement est capable de conduire de grandes oscillations de tension de rendement aux arrêts de 50 Ohm. Afin d’examiner le récepteur, une affiche PCB et une stratégie d’essai conçue avec le circuit est présenté. Des détails au sujet des diverses décisions de conception et défi sont discutés dans cette thèse.

Abstract:
Performance analysis of optical heterodyne receivers in Wavelength Division Multiplexing (WDM) has been an important research area in the last few years. WDM can potentially provide hundreds of Gb/s channels in the same fiber. However, because of channel interference in WDM, performance analysis is important to design the system properly. In this thesis, a detailed noise and jitter analysis has been performed for an optical heterodyne PSK receiver used in WDM. In WDM, noise sources include shot noise, channel interference noise, and phase noise. These noise sources will not only add to the signal, but also cause timing jitter at the bit timing recovery. Expressions for the noise and jitter variances at the detector input are derived for both RZ and NRZ signals. Bit error probabilities as a function of WDM channel separation are computed. It is found that the overall bit error rate performance of RZ is better than NRZ.

Abstract:
In a bid to cope with challenges of increasing demand for higher data rate, better quality of service, and higher network capacity, there is a migration from Single Input Single Output (SISO) antenna technology to a more promising Multiple Input Multiple Output (MIMO) antenna technology. On the other hand, Orthogonal Frequency Division Multiplexing (OFDM) technique has emerged as a very popular multi-carrier modulation technique, thus it is considered as a promising solution to enhance the data rate of future broadband wireless communication systems. The first contribution of this thesis is the development of a low complexity adaptive algorithm that is robust against slow and fast fading channel scenarios, in comparison to the conventional individual parameter estimation by E. Teletar in his famous paper of 1999. Implementing the Adaptive MMSE Receivers in MIMO OFDM systems which I refer to (AMUD MIMO OFDM), combines the adaptive minimum mean square error multiuser receiver's scheme with prior information of the channel and interference cancelation in the spatial domain, achieves enhanced joint channel estimation and signal detection which makes the new technique effectively mobile. A mathematical analysis and simulation results to estimate the Information Capacity of Mobile Communication system with MMSE DFE and OFDM receivers were investigated. The capacity of a stationary channel with ISI is achievable by both the single carrier MMSE DFE and multicarrier modulation over narrow sub channels with OFDM receivers. The achieved capacity result shows that in both techniques single carrier and multicarrier, apart from different implementations are essentially identical when it comes to achievable criteria for information channel capacity. Lastly, AMUD MIMO OFDM were compared with both adaptive vector pre-coding and iterative system and their performance were fantastic, results shows that it will assure transmission over a high channel capacity.

La próxima construcción del radiotelescopio "Cerro Chajnantor Atacama Telescope" (CCAT) traerá enormes desafíos para la instrumentación astronómica. Dentro de estos desafíos se encuentra el "CCAT Heterodyne Array Receiver", un arreglo modular de receptores heterodinos de doble banda con alta resolución espectral. Este se espera sea el primer arreglo de receptores heterodinos con 64 (base) y 128 pixeles (meta), substancialmente mas grande que cualquier arreglo de este tipo actualmente en operación. Sin embargo, estos receptores heterodinos de gran escala solo pueden ser construidos si es posible reducir considerablemente la complejidad de cada pixel. Esta tesis presenta el trabajo realizado en el desarrollo compacto de la electrónica de control de polarización para mezcladores de juntura "Superconductor-Insulator-Superconductor" (SIS) en arreglos heterodinos de gran escala. El objetivo principal de esta tesis corresponde a la programación del microprocesador, en un prototipo de canal singular, de la tarjeta de control de polarización para interactuar con el mezclador, y luego probar su funcionamiento en un setup de laboratorio. El software fue exitósamente programado y fue primero probado en un sistema de prueba para asegurar una interacción sin riesgos con el mezclador. Luego se probó experimentalmente que fue posible suministrar el voltaje de ajuste de alta precisión del mezclador y la corriente del las bobinas de campo magnético para suprimir los efectos de Josephson en el mezclador. Otras funciones específicas como el barrido de voltaje en el mezclador o la habilitación de la conexión con el mezclador también fueron testeadas. El PC de control es capaz de controlar todos estos parámetros y funciones junto con el monitoreo de la corriente y voltaje reales en el mezclador. El rol fundamental de la constante de tiempo electrónica de la tarjeta es presentado en conjunto con un análisis en términos de la distorsión de la curva de voltaje-corriente del mezclador y su influencia en el ruido electrónico. Los resultados muestran, de todas formas, que tanto la distorsión como el ruido se encuentran dentro de un rango adecuado debido al sector donde se espera ajustar el voltaje del mezclador. En conclusión, el software programado en el microprocesador crea una base de instrucciones que permiten al usuario hacer uso de la tarjeta de control de polarización para interactuar con el mezclador de manera segura. Esta interacción le permite realizar una calibración manual (aunque controlada remotamente) del mezclador, obteniendo los mismos resultados que el proceso actual. Esto representa un gran paso adelante en la reducción de la complejidad de hardware del sistema de control de polarización, siendo esto clave para el desarrollo de arreglo de receptores heterodinos de gran escala.

Abstract:
Power consumption requires critical consideration during system design for portable wireless communication devices as it has a direct influence on the battery weight and volume required for operation. Wideband Code Division Multiple Access (W-CDMA) techniques are favoured for use in future generation mobile communication systems. This thesis investigates novel low power techniques for use in system blocks within a W-CDMA adaptive linear minimum mean squared error (LMMSE) receiver architecture. Two low power techniques are presented for reducing power dissipation in the LMS adaptive filter, this being the main power consuming block within this receiver. These low power techniques are namely the decorrelating transform, this is a differential coefficient technique, and the variable length update algorithm which is a dynamic tap-length optimisation technique. The decorrelating transform is based on the principle of reducing the wordlength of filter coefficients by using the computed difference between adjacent coefficients in calculation of the filter output. The effect of reducing the wordlength of filter coefficients being presented to multipliers in the filter is a reduction in switching activity within the multiplier thus reducing power consumed. In the case of the LMS adaptive filter, with coefficients being continuously updated, the decorrelating transform is applied to these calculated coefficients with minimal hardware or computational overhead. The correlation between filter coefficients is exploited to achieve a wordlength reduction from 16 bits down to 10 bits in the FIR filter block. The variable length update algorithm is based on the principle of optimising the number of operational filter taps in the LMS adaptive filter according to operating conditions. The number of taps in operation can be increased or decreased dynamically according to the mean squared error at the output of the filter. This algorithm is used to exploit the fact that when the SNR in the channel is low the minimum mean squared error of the short equaliser is almost the same as that of the longer equaliser. Therefore, minimising the length of the equaliser will not result in poorer MSE performance and there is no disadvantage in having fewer taps in operation. If fewer taps are in operation then switching will not only be reduced in the arithmetic blocks but also in the memory blocks required by the LMS algorithm and FIR filter process. This reduces the power consumed by both these computation intensive functional blocks. Power results are obtained for equaliser lengths from 73 to 16 taps and for operation with varying input SNR. This thesis then proposes that the variable length LMS adaptive filter is applied in the adaptive LMMSE receiver to create a low power implementation. Power consumption in the receiver is reduced by the dynamic optimisation of the LMS receiver coefficient calculation. A considerable power saving is seen to be achieved when moving from a fixed length LMS implementation to the variable length design. All design architectures are coded in Verilog hardware description language at register transfer level (RTL). Once functional specification of the design is verified, synthesis is carried out using either Synopsys DesignCompiler or Cadence BuildGates to create a gate level netlist. Power consumption results are determined at the gate level and estimated using the Synopsys DesignPower tool.

Abstract:
A study of the concepts involved in the bias-stability of log-domain filters is presented. Through a thorough analysis of the factors contributing to the existence of multiple and unstable operating points in log-domain filters, a biquad architecture that overcomes these drawbacks is proposed. This is accompanied with a theoretical verification of both stability and the input-output linear behavior. The study provides a foundation for the design and implementation of other bias-stable log-domain circuits.
This thesis also presents the design of a multistandard channel-select filter for GSM, IS-95, and WCDMA. The filter's tunability extends from 100 kHz to 20.05 MHz. The implemented 6th-order quasi-Butterworth log-domain filter was fabricated in a Silicon Germanium (SiGeHP5) technology, operates from a supply voltage as low as 1.2 V, and consumes a maximum power of 12.9 mW at 20.05 MHz cutoff frequency. Dynamic biasing techniques are employed in order to extend the SFDR of the filter, e.g. from SFDR = 39 dBm to SFDR = 48 dBm at 20.05 MHz cutoff frequency.

High-speed optical systems are becoming increasingly important due to the progress of multimedia communications, which requires ever increasing data-transmission capacity. SONET based systems at 10 Gb/s are under commercial development, and it is likely that systems based on higher SONET hierarchies will soon be required for further broadband communications networks.
This thesis describes a low-noise and low-power Si-bipolar transimpedance preamplifier for the front-end of an optical-fibre receiver using a 0.5 mum 25 GHz self-aligned double poly silicon bipolar process. Design specifications are met through trade-offs between input noise current, speed, transimpedance gain, power dissipation, impedance matching, and supply voltage. This was achieved by (1) using inductors to enhance the bandwidth, (2) using a tuned noise-matching network at the input to improve the signal-to-noise ratio (SNR), (3) and using frequency compensation techniques to improve stability and to further enhance the bandwidth of the preamplifier.
In this thesis, the design of the amplifier is preceded by an analysis of four different circuit topologies, with focus on three main design parameters: bandwidth, input-referred noise, and power dissipation. This is followed by a discussion of the specific bipolar transimpedance amplifier (TIA) designed and fabricated, and the integration of an optoelectronic device model with the preamplifier for the purpose of testing. Design, simulation, layout and test data of the preamplifier are presented in detail. The performance of the TIA is finally discussed based on measurements.

Abstract:
«The electronic magazine with rating system of an estimation of individual and collective work of students» (EM) is developed in document Microsoft Excel with use of macros. EM allows to automate all the calculated operations connected with estimation of amount scored by students in each form of the current control. EM provides automatic calculation of rating of the student with reflection of a maximum quantity of the points received in given educational group. The rating equal to “1” is assigned to the student who has got a maximum quantity of points for the certain date. For the other students the share of their points in this maximum size is indicated. The choice of an estimation is made in an alphabetic format according to requirements of the European translation system of test units for the international recognition of results of educational outcomes (ECTS - European Credit Transfer System), by use of a corresponding scale of an estimation. The list of students is placed on the first page of magazine and automatically displayed on all subsequent pages. For each page of magazine the optimal size of document printing is set with automatic enter of current date and time. Owing to accounting rate of complexity of task EM is the universal technical tool which can be used for any subject matter.

Abstract:
The Annual Report on Migration and Asylum 2016 provides an overview of trends, policy developments and significant debates in the area of asylum and migration during 2016 in Ireland. Some important developments in 2016 included: The International Protection Act 2015 was commenced throughout 2016. The single application procedure under the Act came into operation from 31 December 2016. The International Protection Office (IPO) replaced the Office of the Refugee Applications Commissioner (ORAC) from 31 December 2016. The first instance appeals body, the International Protection Appeals Tribunal (IPAT), replacing the Refugee Appeals Tribunal (RAT), was established on 31 December 2016. An online appointments system for all registrations at the Registration Office in Dublin was introduced. An electronic Employment Permits Online System (EPOS) was introduced. The Irish Short Stay Visa Waiver Programme was extended for a further five years to October 2021. The Second National Action Plan to Prevent and Combat Human Trafficking was published. 2016 was the first full year of implementation of the Irish Refugee Protection Programme (IRPP). A total of 240 persons were relocated to Ireland from Greece under the relocation strand of the programme and 356 persons were resettled to Ireland. Following an Oireachtas motion, the Government agreed to allocate up to 200 places to unaccompanied minors who had been living in the former migrant camp in Calais and who expressed a wish to come to Ireland. This figure is included in the overall total under the IRPP. Ireland and Jordan were appointed as co-facilitators in February 2016 to conduct preparatory negotiations for the UN high level Summit for Refugees and Migrants. The New York Declaration, of September 2016, sets out plans to start negotiations for a global compact for safe, orderly and regular migration and a global compact for refugees to be adopted in 2018. Key figures for 2016: There were approximately 115,000 non-EEA nationals with permission to remain in Ireland in 2016 compared to 114,000 at the end of 2015. Net inward migration for non-EU nationals is estimated to be 15,700. The number of newly arriving immigrants increased year-on-year to 84,600 at April 2017 from 82,300 at end April 2016. Non-EU nationals represented 34.8 per cent of this total at end April 2017. A total of 104,572 visas, both long stay and short stay, were issued in 2016. Approximately 4,127 persons were refused entry to Ireland at the external borders. Of these, 396 were subsequently admitted to pursue a protection application. 428 persons were returned from Ireland as part of forced return measures, with 187 availing of voluntary return, of which 143 were assisted by the International Organization for Migration Assisted Voluntary Return Programme. There were 532 permissions of leave to remain granted under section 3 of the Immigration Act 1999 during 2016. A total of 2,244 applications for refugee status were received in 2016, a drop of 32 per cent from 2015 (3,276). 641 subsidiary protection cases were processed and 431 new applications for subsidiary protection were submitted. 358 applications for family reunification in respect of recognised refugees were received. A total of 95 alleged trafficking victims were identified, compared with 78 in 2015.
