Data Mining Strategies for Real-Time Control in New York City
استراتژی داده کاوی برای کنترل زمان واقعی در شهر نیویورک-2105 The Data Mining System (DMS) at New York City Department of Transportation (NYCDOT) mainly consists of four database
systems for traffic and pedestrian/bicycle volumes, crash data, and signal timing plans as well as the Midtown in Motion (MIM)
systems which are used as part of the NYCDOT Intelligent Transportation System (ITS) infrastructure. These database and
control systems are operated by different units at NYCDOT as an independent database or operation system. New York City
experiences heavy traffic volumes, pedestrians and cyclists in each Central Business District (CBD) area and along key arterial
systems. There are consistent and urgent needs in New York City for real-time control to improve mobility and safety for all
users of the street networks, and to provide a timely response and management of random incidents. Therefore, it is necessary to
develop an integrated DMS for effective real-time control and active transportation management (ATM) in New York City.
This paper will present new strategies for New York City suggesting the development of efficient and cost-effective DMS,
involving: 1) use of new technology applications such as tablets and smartphone with Global Positioning System (GPS) and
wireless communication features for data collection and reduction; 2) interface development among existing database and control
systems; and 3) integrated DMS deployment with macroscopic and mesoscopic simulation models in Manhattan. This study
paper also suggests a complete data mining process for real-time control with traditional static data, current real timing data from
loop detectors, microwave sensors, and video cameras, and new real-time data using the GPS data. GPS data, including using taxi
and bus GPS information, and smartphone applications can be obtained in all weather conditions and during anytime of the day.
GPS data and smartphone application in NYCDOT DMS is discussed herein as a new concept.

Decentralization Using Quantum Blockchain: A Theoretical Analysis
تمرکززدایی با استفاده از بلاک چین کوانتومی: یک تحلیل نظری-2022 Blockchain technology has been prominent recently due to its applications in cryptocurrency. Numerous decentralized blockchain applications have been possible due to blockchains’ nature of
distributed, secured, and peer-to-peer storage. One of its technical pillars is using public-key cryptography
and hash functions, which promise a secure, pseudoanonymous, and distributed storage with nonrepudiation.
This security is believed to be difficult to break with classical computational powers. However, recent
advances in quantum computing have raised the possibility of breaking these algorithms with quantum
computers, thus, threatening the blockchains’ security. Quantum-resistant blockchains are being proposed
as alternatives to resolve this issue. Some propose to replace traditional cryptography with postquantum
cryptography—others base their approaches on quantum computer networks or quantum internets. Nonetheless, a new security infrastructure (e.g., access control/authentication) must be established before any of
these could happen. This article provides a theoretical analysis of the quantum blockchain technologies
that could be used for decentralized identity authentication. We put together a conceptual design for a
quantum blockchain identity framework and give a review of the technical evidence. We investigate its
essential components and feasibility, effectiveness, and limitations. Even though it currently has various
limitations and challenges, we believe a decentralized perspective of quantum applications is noteworthy and
likely.

Deep Reinforcement Learning With Quantum-Inspired Experience Replay
یادگیری تقویتی عمیق با تکرار تجربه کوانتومی-2022 In this article, a novel training paradigm inspired
by quantum computation is proposed for deep reinforcement
learning (DRL) with experience replay. In contrast to the traditional experience replay mechanism in DRL, the proposed DRL
with quantum-inspired experience replay (DRL-QER) adaptively
chooses experiences from the replay buffer according to the
complexity and the replayed times of each experience (also
called transition), to achieve a balance between exploration and
exploitation. In DRL-QER, transitions are first formulated in
quantum representations and then the preparation operation
and depreciation operation are performed on the transitions.
In this process, the preparation operation reflects the relationship between the temporal-difference errors (TD-errors) and the
importance of the experiences, while the depreciation operation is
taken into account to ensure the diversity of the transitions. The
experimental results on Atari 2600 games show that DRL-QER
outperforms state-of-the-art algorithms, such as DRL-PER and
DCRL on most of these games with improved training efficiency
and is also applicable to such memory-based DRL approaches
as double network and dueling network.

Internet of Things-enabled Passive Contact Tracing in Smart Cities
ردیابی تماس غیرفعال با قابلیت اینترنت اشیا در شهرهای هوشمند-2022 Contact tracing has been proven an essential practice during pandemic outbreaks and is a
critical non-pharmaceutical intervention to reduce mortality rates. While traditional con-
tact tracing approaches are gradually being replaced by peer-to-peer smartphone-based
systems, the new applications tend to ignore the Internet-of-Things (IoT) ecosystem that is
steadily growing in smart city environments. This work presents a contact tracing frame-
work that logs smart space users’ co-existence using IoT devices as reference anchors. The
design is non-intrusive as it relies on passive wireless interactions between each user’s
carried equipment (e.g., smartphone, wearable, proximity card) with an IoT device by uti-
lizing received signal strength indicators (RSSI). The proposed framework can log the iden-
tities for the interacting pair, their estimated distance, and the overlapping time duration.
Also, we propose a machine learning-based infection risk classification method to char-
acterize each interaction that relies on RSSI-based attributes and contact details. Finally,
the proposed contact tracing framework’s performance is evaluated through a real-world
case study of actual wireless interactions between users and IoT devices through Bluetooth
Low Energy advertising. The results demonstrate the system’s capability to accurately cap-
ture contact between mobile users and assess their infection risk provided adequate model
training over time.

Deployment-Ready Quantum Key Distribution Over a Classical Network Infrastructure in Padua
توزیع کلید کوانتومی آماده استقرار بر روی یک زیرساخت شبکه کلاسیک در پادوآ-2022 Current technological progress is driving Quantum
Key Distribution towards a commercial and worldwide scale
expansion. Its capability to deliver secure communication
regardless of the computational power of the attackers will be a
fundamental feature in the next generations of telecommunication
networks. Nevertheless, demonstrations of QKD implementation in a real operating scenario and their coexistence with the
classical telecom infrastructure are of fundamental importance
for reliable exploitation. Here we present a Quantum Key
Distribution application implemented over a classical fiber-based
infrastructure. We exploit a 50 MHz source at 1550 nm, a single 13
km-long fiber cable for both the quantum and the classical channel,
and a simplified receiver scheme with just one single-photon
detector. In this way, we achieve an error rate of approximately
2% and a secret key rate of about 1.7 kbps, thus demonstrating the
feasibility of low-cost and ready-to-use Quantum Key Distribution
systems compatible with standard classical infrastructure.

IoT architecture for continuous long term monitoring: Parkinson’s Disease case study
معماری اینترنت اشیا برای نظارت طولانی مدت مداوم: مطالعه موردی بیماری پارکینسون-2022 In recent years, technological advancements and the strengthening of the Internet of Things
concepts have led to significant improvements in the technology infrastructures for remote
monitoring. This includes telemedicine which is the ensemble of technologies and tools involved
in medical services, from consultations, to diagnosis, prescriptions, treatment and patient
monitoring, all done remotely via an Internet connection.
Developing a telemedicine framework capable of monitoring patients over a continuous long-term monitoring window may encounter various issues related to the battery life of the device or the accuracy of the retrieved data. Moreover, it is crucial to develop an IoT architecture that is adaptable to various scenarios and the ongoing changes of the application scenario under analysis. In this work, we present an IoT architecture for continuous long-term monitoring of patients. Furthermore, as a real scenario case study, we adapt our IoT architecture for Parkinson’s Disease management, building up the PDRMA (Parkinson’s disease remote monitoring architecture). Performance analysis for optimal operation with respect to temperature and daily battery life is conducted. Finally, a multi-parameter app for the continuous monitoring of Parkinson’s patients is presented. keywords: IoT | Telemedicine | Continuous long term monitoring | Parkinson’s disease | e-Health |

Direct Quantum Communications in the Presence of Realistic Noisy Entanglement
ارتباطات کوانتومی مستقیم در حضور درهم تنیدگی پر سر و صدا واقعی-2022 To realize the Quantum Internet, quantum
communications require pre-shared entanglement among quantum nodes. However, both the generation and the distribution
of the maximally-entangled quantum states are inherently contaminated by quantum decoherence. Conventionally, the quantum
decoherence is mitigated by performing the consecutive steps of
quantum entanglement distillation followed by quantum teleportation. However, this conventional approach imposes a long delay.
To circumvent this impediment, we propose a novel quantum
communication scheme relying on realistic noisy pre-shared
entanglement, which eliminates the sequential steps imposing
delay in the standard approach. More precisely, our proposed
scheme can be viewed as a direct quantum communication
scheme capable of improving the quantum bit error ratio (QBER)
of the logical qubits despite relying on realistic noisy pre-shared
entanglement. Our performance analysis shows that the proposed
scheme offers competitive QBER, yield, and goodput compared
to the existing state-of-the-art quantum communication schemes,
despite requiring fewer quantum gates.
