description: The political and social interaction between the Ottoman Empire and Kurdish tribes, which can be traced back to the first quarter of the 16th century, continued until the modern republic with various continuities and ruptures. This multi-dimensional and complex relationship was neither in the form of absolute loyalty to the sultan, and thus to the Islamic caliph on a religious basis, nor a constant revolt against the authority of the empire in order to preserve their autonomy. Until the beginning of the 20th century, tribes were not only structures used by the Ottoman, Safavid, and Russian empires for their own interests. They were also organizations capable of dominating a certain geographical area and had a vital potential to constantly generate violence and extend it to the empires and even between one another. Contrary to the state, which systematically and regularly perpetrated this violence and institutionalized and justified itself through the monopoly of violence, their inability to do so did not necessarily mean that they were not genuine political organizations and did not have their own agenda. This study, conducted largely in light of archival documents and Ottoman primary sources, aims to examine the boundaries of loyalty and rebellion in the oscillating relationship between Kurdish tribes and the Turkish state.

description: We revisit nonsingular cosmologies in which the limiting curvature hypothesis is realized. We study the cosmological perturbations of the theory and determine the general criteria for stability. For the simplest model, we find generic Ostrogradski instabilities unless the action contains the Weyl tensor squared with the appropriate coefficient. When considering two specific nonsingular cosmological scenarios(one inflationary and one genesis model), we find ghost and gradient instabilities throughout most of the cosmic evolution. Furthermore, we show that the theory is equivalent to a theory of gravity where the action is a general function of the Ricci and Gauss-Bonnet scalars, and this type of theory is known to suffer from instabilities in anisotropic backgrounds. This leads us to construct a new type of curvature invariant scalar function. We show that it does not have Ostrogradski instabilities, and it avoids ghost and gradient instabilities for most of the interesting background inflationary and genesis trajectories. We further show that it does not possess additional new degrees of freedom in an anisotropic spacetime. This opens the door for studying stable alternative nonsingular very early universe cosmologies.

description: Most of the recent academic literature has focused on the macro politics of the Kurdish situation within Iraq and there is little scholarship about the younger generation of Kurds coming of age during the autonomous Kurdish rule. Unlike their forebears, they have no direct memory of the decades-long repression campaigns. For them, the history starts with the inception of a semi-autonomous Kurdish enclave and de facto self-rule after the first Gulf War in 1991. Studying ‘Generation 2000’, the Kurdish millennials who came of age in the aftermath of the United States invasion of Iraq in 2003 offers vital insights into the dynamics of a region that experienced great socio-political transformation.

description: The integration of language instructions with robotic control, particularly through Vision Language Action (VLA) models, has shown significant potential. However, these systems are often hindered by high computational costs, the need for extensive retraining, and limited scalability, making them less accessible for widespread use.
 In this paper, we introduce SVLR (Scalable Visual Language Robotics), an open-source, modular framework that operates without the need for retraining, providing a scalable solution for robotic control. SVLR leverages a combination of lightweight, open-source AI models including the Vision-Language Model (VLM) Mini-InternVL, zero-shot image segmentation model CLIPSeg, Large Language Model Phi-3, and sentence similarity model all-MiniLM to process visual and language inputs. These models work together to identify objects in an unknown environment, use them as parameters for task execution, and generate a sequence of actions in response to natural language instructions. A key strength of SVLR is its scalability. The framework allows for easy integration of new robotic tasks and robots by simply adding text descriptions and task definitions, without the need for retraining. This modularity ensures that SVLR can continuously adapt to the latest advancements in AI technologies and support a wide range of robots and tasks.
 SVLR operates effectively on an NVIDIA RTX 2070 (mobile) GPU, demonstrating promising performance in executing pick-and-place tasks. While these initial results are encouraging, further evaluation across a broader set of tasks and comparisons with existing VLA models are needed to assess SVLR's generalization capabilities and performance in more complex scenarios.

description: The half-life of the neutron-rich nuclide, {\fesixty} has been in dispute in recent years. A measurement in 2009 published a value of $(2.62 \pm 0.04)\times10^{6}$ years, almost twice that of the previously accepted value from 1984 of $(1.49 \pm 0.27)\times10^{6}$ years. This longer half-life was confirmed in 2015 by a second measurement, resulting in a value of $(2.50 \pm 0.12)\times10^{6}$ years. All three half-life measurements used the grow-in of the $γ$-ray lines in {\nisixty} from the decay of the ground state of $^{60}\text{Co}$ (t$_{1/2}$=5.27 years) to determine the activity of a sample with a known number of {\fesixty} atoms. In contrast, the work presented here measured the {\fesixty} activity directly via the 58.6 keV $γ$-ray line from the short-lived isomeric state of $^{60}\text{Co}$ (t$_{1/2}$=10.5 minutes), thus being independent of any possible contamination from long-lived $^{60\text{g}}\text{Co}$. A fraction of the material from the 2015 experiment with a known number of {\fesixty} atoms was used for the activity measurement, resulting in a half-life value of $(2.72 \pm 0.16)\times10^{6}$ years, confirming again the longer half-life. In addition, {\fesixty}/{\fe} isotopic ratios of samples with two different dilutions of this material were measured with Accelerator Mass Spectrometry (AMS) to determine the number of {\fesixty} atoms. Combining this with our activity measurement resulted in a half-life value of $(2.69 \pm 0.28)\times 10^{6}$ years, again agreeing with the longer half-life.

The Politics of Negotiating the Kurdish Self-Determination Conflict: Failure by Design?
Creators: name: Bezwan, Naif
Publisher: name: International Journal of Conflict and Violence (IJCV)
Year: 2022

description: This study explores the long-standing conflict over Kurdish self-determination as it played out in three cases of negotiations conducted between the governments of Iraq, Iran, and Turkey, and the representatives of Kurdish movements from the 1970s onwards. Drawing on conflict and negotiations studies, the paper seeks to explain (a) why efforts at negotiating the conflict in question have not been successful and (b) what reasons account for this failure. To this end, the study first conceptualizes the Kurdish question as a constitutive conflict of self-determination grounded in a dynamic contest between direct rule and self-rule. Second, it systematically links the failure of negotiations to the absence of substantive commitments by the states involved, the lack of collective action on the part of the Kurdish actors, and negative third-party involvement. The objective is to provide a theoretically guided and empirically informed conceptual approach to the failed politics of negotiating the Kurdish self-determination conflict.

description: We investigate the impact of choosing regressors and molecular representations for the construction of fast machine learning (ML) models of thirteen electronic ground-state properties of organic molecules. The performance of each regressor/representation/property combination is assessed using learning curves which report out-of-sample errors as a function of training set size with up to $\sim$117k distinct molecules. Molecular structures and properties at hybrid density functional theory (DFT) level of theory used for training and testing come from the QM9 database [Ramakrishnan et al, {\em Scientific Data} {\bf 1} 140022 (2014)] and include dipole moment, polarizability, HOMO/LUMO energies and gap, electronic spatial extent, zero point vibrational energy, enthalpies and free energies of atomization, heat capacity and the highest fundamental vibrational frequency. Various representations from the literature have been studied (Coulomb matrix, bag of bonds, BAML and ECFP4, molecular graphs (MG)), as well as newly developed distribution based variants including histograms of distances (HD), and angles (HDA/MARAD), and dihedrals (HDAD). Regressors include linear models (Bayesian ridge regression (BR) and linear regression with elastic net regularization (EN)), random forest (RF), kernel ridge regression (KRR) and two types of neural net works, graph convolutions (GC) and gated graph networks (GG). We present numerical evidence that ML model predictions deviate from DFT less than DFT deviates from experiment for all properties. Furthermore, our out-of-sample prediction errors with respect to hybrid DFT reference are on par with, or close to, chemical accuracy. Our findings suggest that ML models could be more accurate than hybrid DFT if explicitly electron correlated quantum (or experimental) data was available.
Rethinking Internal Colonialism: Radicalization of the Kurdish Movement in Turkey
Creators: name: Tuğrul, Barış
Publisher: name: International Journal of Conflict and Violence (IJCV)
Year: 2022

description: The thesis of internal colonialism offers a controversial center-periphery approach to the diffusion model when explaining the persistence of peripheral ethnic identities in Western nation-states. Associating persistent nationalist mobilization in the ethnically different peripheral regions with the cultural division of labor showed some potential in explaining the cases observed in the British Isles, Brittany and Quebec. In some other cases with solid peripheral national economies, such as Basque Country and Catalonia, however, the thesis of internal colonialism was considered paradoxical and became the target of criticism. This study examines the role of internal colonialism in the radicalization of the Kurdish movement in Turkey. The empirical field research based on in-depth interviews with PKK militants from three consecutive generations provides qualitative evidence regarding the impacts of colonial settings in this process. Social consequences emerging from internal colonialism constitute an essential motivation and justification expressed by actors involved in armed struggle against what they define as Turkish colonial rule.

ARE WOMEN'S SHORT-TERM MATING BEHAVIORS JUST A FUNCTION OF A LONG-TERM MATING STRATEGY?

description: Studies on women’s mating strategies have demonstrated that women engage in short-term mating (STM) for long-term mating (LTM) benefits (e.g., mate assessment) and for non-LTM related benefits (e.g., protection). Yet, it is currently unclear the extent to which each of these benefits individually explains women’s STM strategy. I tested eight of these benefits through a descriptive survey, which asked mating-related questions to 361 women regarding their five most recent sexual partners (n = 854). I found that 76% of women’s five most recent sexual partners occurred in the context of LTM. Additionally, for all sexual partners each woman reported, 66% of women pursued an LTM strategy, 31% pursued a mixed mating strategy, and 3% pursued an STM strategy. The benefits women most expected to receive from each uncommitted sexual partner reported included mate assessment (50%), preference clarification (45%), protection (44%), help and assistance (resources; 42%), new friends or social circles (status; 35%), mate acquisition (35%), honing skills of mate attraction (31%), status elevation (20%), and mate switching (19%). I also found that women who elevated their status as a result of an STM, who expected protection from their short-term mating partner, and who expected to replace their long-term partner with their short-term partner were statistically less likely to experience sexual regret than women who did not elevate status, did not expect protection, and did not expect to replace their long-term partner. Overall, on average, women are more inclined to pursue an LTM than an STM strategy. Additionally, the two benefits women most expect to receive from STM relationships are mate assessment and preference clarification, both long-term mating-related benefits.

description: Let S be a Noetherian scheme and f:X -> S a proper morphism. By SGA 4 XIV, for any constructible sheaf F of Z/nZ-modules on X, the sheaves of Z/nZ-modules R^if_*F obtained by direct image (for the etale topology) are also constructible: there is a stratification of S on whose strata these sheaves are locally constant constructible. After previous work of N. Katz and G. Laumon, or L. Illusie, on the special case in which S is generically of characteristic zero or the sheaves F are constant (with invertible torsion on S), here we study the dependency of the stratification on F. We show that a natural "uniform" tameness and constructibility condition satisfied by constant sheaves, which was introduced by O. Gabber, is stable under the functors R^if_*. If f is not proper, this result still holds assuming tameness at infinity, relatively to S. We also prove the existence of uniform bounds on Betti numbers, in particular for the stalks of the sheaves R^if_*Z/lZ, where l ranges through all prime numbers invertible on S.

Publisher: name: International Journal of Conflict and Violence (IJCV)
Year: 2022

description: This article focuses the emergence of and need for alternative governmentality and Kurdish non-state justice under a conflicted and authoritarian state. It analyses how and why Kurdish de facto judges operate and negotiate prevailing power relations, illustrating the practice of the Kurdish alternative court system before 2000, and the development of local justice in Kurdish towns and cities after 2000. The article maps out the diverse and varied scene of Kurdish parallel justice procedures and mechanisms. The gendered demands and activities of key actors and beneficiaries are analysed, and relations, tensions and political rifts beyond the actual court procedures explored. The article sheds light on the different obstacles and challenges facing women and men under local justice, while also paying attention to ethnic and religious diversities. In this article, the examination of the state and understanding the everyday life of regular people are mainly based on direct ethnographical accounts.

Path Dependence from Proxy Agent to De Facto State: A History of ‘Strategic Exploitation’ of the Kurds as a Context of the Iraqi Kurdistan Security Policy
Creators: name: Sosnowski, Piotr
Publisher: name: International Journal of Conflict and Violence (IJCV)
Year: 2022

description: The scientific goal of this paper is to conceptualize the phenomenon of ‘strategic exploitation’ of Kurdish political entities and to investigate it as a process that triggered the change in Kurdish actorness from isolated non-state to de facto state. Covering two centuries, the contribution examines actorness and cases of patron-client relations between Kurdish political entities and sovereign states. It answers the question: What was the path of strategic exploitation of the Kurdish political entities and how does it affect the contemporary security policy of Iraqi Kurdistan? Combining the concepts of proxy war, de facto state, and path dependence, it argues that the persistent experience of strategic exploitation shaped the collective strategic thought of Kurdish political entities and has a visible impact on contemporary Iraqi Kurdistan security policy. It applies the process-tracing method based on an analysis of literature on the history of Kurds and Kurdistan to investigate patron-client relations and variability of actorness. The article concludes that the experience of ‘strategic exploitation’ has shaped the main direction of Iraqi Kurdistan security policy. It is expressed in practice as abstaining from an official declaration of secession and diversifying relations with external actors.

A consensus seems to be emerging that, in addition to the standard scenario of particle acceleration via the Fermi process at the termination shock of the pulsar wind, magnetic reconnection in the wind, at the termination shock and in the Nebula plays a major role in powering the multi-wavelength signatures of PWNe.

description: We analyze the inspiral dynamics of equal-mass precessing black-hole binaries using multi-timescale techniques. The orbit-averaged post-Newtonian evolutionary equations admit two constants of motion in the equal-mass limit, namely the magnitude of the total spin $S$ and the effective spin $ξ$. This feature makes the entire dynamics qualitatively different compared to the generic unequal-mass case, where only $ξ$ is constant while the variable $S$ parametrizes the precession dynamics. For fixed individual masses and spin magnitudes, an equal-mass black-hole inspiral is uniquely characterized by the two parameters $(S,ξ)$: these two numbers completely determine the entire evolution under the effect of radiation reaction. In particular, for equal-mass binaries we find that (i) the black-hole binary spin morphology is constant throughout the inspiral, and that (ii) the precessional motion of the two black-hole spins about the total spin takes place on a longer timescale than the precession of the total spin and the orbital plane about the total angular momentum.

description: According to the conjecture "complexity equals action," the complexity of a holographic state is equal to the action of a Wheeler-DeWitt (WDW) patch of black holes in anti-de Sitter space. In this paper we calculate the action growth of charged black holes with a single horizon, paying attention to the contribution from a spacelike singularity inside the horizon. We consider two kinds of such charged black holes: one is a charged dilaton black hole, and the other is a Born-Infeld black hole with $β^2 Q^2<1/4$. In both cases, although an electric charge appears in the black hole solutions, the inner horizon is absent, instead a spacelike singularity appears inside the horizon. We find that the action growth of the WDW patch of the charged black hole is finite and satisfies the Lloyd bound. As a check, we also calculate the action growth of a charged black hole with a phantom Maxwell field. In this case, although the contributions from the bulk integral and the spacelike singularity are individually divergent, these two divergences just cancel each other and a finite action growth is obtained. But in this case, the Lloyd bound is violated as expected.

The Road to Sèvres: Kurdish Elites and Question of Self-Determination After the First World War
Creators: name: Atmaca, Metin
Publisher: name: International Journal of Conflict and Violence (IJCV)
Year: 2022

description: This paper focuses on Kurdish elites and their quest for a Kurdish state during the Peace Conference that took place in Paris after the First World War. Cross-examining the British, French, Kurdish, and Ottoman sources, this paper shows that despite the failure to establish a Kurdish state in the aftermath of the disintegration of the Ottoman Empire the Kurdish elites, with their diplomatic and political experience and networking had equal, sometimes better, capacity to the leaders of other delegations in the Peace Conference. To demonstrate this, I focus on Kurdish elites, who were experienced in the imperial statecraft, especially Şerif Pasha, Sheikh Abdulkadir, Emin Ali Bedirhan, and Süreyya Bedirhan, lay out the complex relations amongst them and describe their efforts to represent the Kurds from the beginning of the Peace Conference until ratification of Treaty of Sèvres on 10 August 1920. In spite of what the available literature suggests, Kurdish elites, using all the available tools at their disposal, negotiated effectively for a Kurdish state. The contribution shows that the Kurdish elites not only presented a series of arguments during the Peace Conference but also laid down the basis for the Kurdish nationalism of the decades to come, with a historical narrative and a cartographic imaginary.

description: The $p_\perp$ dependence of the nuclear modification factor $R_{\rm AA}$ measured in PbPb collisions at the LHC exhibits a universal shape, which can be very well reproduced in a simple energy loss model based on the BDMPS medium-induced gluon spectrum. The scaling is observed for various hadron species ($h^\pm$, $D$, $J/ψ$) in different centrality classes and at both colliding energies, $\sqrt{s}=2.76$ TeV and $\sqrt{s}=5.02$ TeV. Results indicate an 10-20% increase of the transport coefficient from $\sqrt{s}=2.76$ TeV to $\sqrt{s}=5.02$ TeV, consistent with that of particle multiplicity. Based on this model, a data-driven procedure is suggested, which allows for the determination of the first and second moments of the quenching weight without any prior knowledge of the latter.

description: To investigate the wall-cooling effects on shock wave turbulent/boundary layer interaction (SWTBLI) with limited experimental data, a supersonic wind tunnel wall was cooled using liquid nitrogen as the cryogenic coolant. Under the condition of the mainstream Mach number, in the range of 2.02-2.04, the wall temperature was cooled to 88-92 K, corresponding to a wall-to-recovery temperature ratio of 0.31-0.33. The flow structures with and without wall cooling were observed using the schlieren method. The reflected shock motion or interaction length in the schlieren image suggested that boundary layer separation was suppressed under the cooling condition in relation to that under the non-cooling condition, and the suppressed ratio of the cooling-to-uncooling interaction length was approximately 0.60-0.72. Additionally, while the mainstream state and wall temperature near the separation were constant, a gradual change in the separated flow field was observed under the wall-cooling condition. This was due to the slow wall temperature increase in the upstream wall of the separation region, where the incoming boundary layer developed. Each flow field of SWTBLI in the present experiment, using liquid nitrogen as the cryogenic coolant, was consistent with the classical Chaman's free interaction theory.

Proposal of highly efficient photoemitter with strong photon-harvesting capability and exciton superradiance

description: We propose a system of highly efficient photoemitters comprising metal-dielectric (plasmonic-excitonic) multilayered structures. In the proposed structure, the absorption in the excitonic layer is greatly enhanced through quantum interference between the split modes arising from the coupling of the layered excitons and the plasmons sustained by the metallic layer. Furthermore, the large interaction volume between surface plasmons and excitons causes exciton superradiance, which results in the extremely efficient photoemission. This finding indicates the possibility of designing highly efficient photoemitters based on simple layered structures.

description: The conventional theory of burning works well in the case of uniform media where all system parameters are spatially independent. We develop a theory of burning in disordered media. In this case, rare regions (hot spots) where the burning process is more effective than on average may control the heat propagation in an explosive sample. We show that most predictions of the theory of burning are quite different from the conventional case. In particular, we show that a system of randomly distributed hot spots exhibits a dynamic phase transition, which is similar to the percolation transition. Depending on parameters of the system the phase transition can be either first or second order. These two regimes are separated by a tricritical point. The above results may be applicable to dynamics of any over-heated disordered system with a first order phase transition.

Civic Culture and Support for Democracy amongst Kurds in Iran, Iraq, and Turkey
Creators: name: Jasim, Dastan

Year: 2022

description: Theories of civic culture and democratization have tended to ignore stateless nations like the Kurds. This brings up the question of what civic culture looks like for these groups and whether the status of statelessness has influenced the civic culture of Kurds in Iran, Iraq, and Turkey. Analyzing the first merged large-N dataset including Kurds from Turkey, Iran, and Iraq, this paper shows that the last hundred years of Kurdish political movements have strongly influenced the civic culture of Kurds. Being Kurdish in Turkey, Iran, and Iraq has a significant effect on levels of political trust and support as well as the correlation of these indicators with levels of support for a democratic political system. Overall, this paper finds that being Kurdish has a strong positive effect on support for democracy versus autocracy in all three countries.

description: We perform a static analysis of a circular cylinder that forms a barrier between surfactant-laden and surfactant-free portions of a liquid$-$gas interface. In addition to determining the general implications of the balances for forces and torques, we quantify how the imbalance $Δγ=γ_a-γ_b$ between the uniform surface tension $γ_a$ of the surfactant-free portion of the interface and the uniform surface tension $γ_b$ of the surfactant-laden portion of the interface influences the load-bearing capacity of a hydrophobic cylinder. Moreover, we demonstrate that the difference between surface tensions on either side of a cylinder with a cross-section of arbitrary shape induces a horizontal force component $f^h$ equal to $Δγ$ in magnitude, when measured per unit length of the cylinder. With an energetic argument, we show that this relation also applies to rod-like barriers with cross-sections of variable shape. In addition, we apply our analysis to amphiphilic Janus cylinders and we discuss practical implications of our findings for Marangoni propulsion and surface pressure measurements.
Noise-induced transitions in a double-well excitable oscillator
Creators: name: Semenov, Vladimir V.
Publisher: name: arXiv
Year: 2017
Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)
subject: FOS: Physical sciences

description: The model of a double-well oscillator with nonlinear dissipation is studied. The self-sustained oscillations regime and the excitable one are described. The first regime consists in the coexistence of two stable limit cycles in the phase space, which correspond to the self-sustained oscillations of the point mass in either potential well. The self-sustained oscillations do not occur in a noise-free system in the excitable regime, but appropriate conditions for coherence resonance in either potential well can be achieved. The stochastic dynamics in both two regimes is researched by using numerical simulation and electronic circuit implementation of the considered system. Multiple qualitative changes of the probability density function (PDF) caused by noise intensity varying are explained by using the phase space structure of the deterministic system.

description: The fraction of binary stars (fb) is one of most valuable tool to probe the star formation and evolution of multiple systems in the Galaxy. We focus on the relationship between fb and stellar metallicity ([Fe/H]) by employing the differential radial velocity (DRV) method and the large sample observed by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). Main-sequence stars from A- to K-types in the third data release (DR3) of LAMOST are selected to estimate fb. Contributions to a profile of DRV from radial velocity (RV) error of single stars (σ) and orbital motion of binary stars are evaluated from the profile of DRV. Finally, we employ 365,911 stars with randomly repeating spectral observations to present a detailed analysis of fb and σin the two-dimensional (2D) space of Teff and [Fe/H]. The A-type stars are more likely to be companions in binary star systems than other stars. Furthermore, the reverse correlation between fb and [Fe/H] can be shown statistically, which suggests that fb is a joint function of Teff and [Fe/H]. At the same time, σof the sample for different Teff and [Fe/H] are fitted. Metal-rich cold stars in our sample have the best RV measurement.

Direct method for measuring and witnessing quantum entanglement of arbitrary two-qubit states through Hong-Ou-Mandel interference

description: We describe a direct method for experimental determination of the negativity of an arbitrary two-qubit state with 11 measurements performed on multiple copies of the two-qubit system. Our method is based on the experimentally accessible sequences of singlet projections performed on up to four qubit pairs. In particular, our method permits the application of the Peres-Horodecki separability criterion to an arbitrary two-qubit state. We explicitly demonstrate that measuring entanglement in terms of negativity requires three measurements more than detecting two-qubit entanglement. The reported minimal set of interferometric measurements provides a complete description of bipartite quantum entanglement in terms of two-photon interference. This set is smaller than the set of 15 measurements needed to perform a complete quantum state tomography of an arbitrary two-qubit system. Finally, we demonstrate that the set of 9 Makhlin's invariants needed to express the negativity can be measured by performing 13 multicopy projections. We demonstrate that these invariants are both a useful theoretical concept for designing specialized quantum interferometers and that their direct measurement within the framework of linear optics does not require performing complete quantum state tomography.

DYNAMIC TRAFFIC LIGHT CONTROL SCHEME FOR REDUCING CO2EMISSIONS EMPLOYING ETC TECHNOLOGY
Creators: name: IJMVSC
Publisher: name: Zenodo
Year: 2011

description: With the increasing growth of vehicle numbers in the world, Global warming is becoming a serious issue. Vehicle CO2 emissions are considered to be one of the main sources of global warming. In order to reduce vehicles CO2 emissions, a dynamic traffic light control scheme is proposed. In the proposed scheme, we are the first to use Electronic Toll Collection (ETC) devices to obtain real time traffic flow information for a traffic control centre. By the proposed scheme, vehicles can pass through intersections with less waiting time and fewer numbers of stops. By smoothing vehicle travel, CO2 emissions can be reduced. Compared with fixed time control, the simulation results indicate that the proposed scheme has much better performance: vehicle average waiting time is greatly reduced and CO2 emissions can also be reduced.
